A King in crisis, a Queen on trial, a Kingdom’s survival hangs in the balance.

Londonia, AD835
The deadly conspiracy against the children of Ealdorman Coenwulf is to be resolved. Those involved have been unmasked and arrested. But will justice prevail?

While the court convenes to determine the conspirator’s fate, King Wiglaf’s position is precarious. His wife, Queen Cynethryth, has been implicated in the plot and while Wiglaf must remain impartial, enemies of the Mercia still conspire to prevent the full truth from ever being known.

As Merica weeps from the betrayal of those close to the King, the greedy eyes of Lord Æthelwulf, King Ecgberht of Wessex’s son, pivot once more towards Mercia. He will stop at nothing to accomplish his goal of ending Mercia’s ruling bloodline.

Mercia once more stands poised to be invaded, but this time not by the Viking raiders they so fear.

Can Icel and his fellow warriors’ triumph as Mercia once more faces betrayal from within?

I'm an author of historical fiction (Early English (before 1066)/Viking) and now five 20th-century mysteries..

The Eagle of Mercia Chronicles (featuring a young Icel from The Last King series) is now available from Boldwood Books. As is the complete Brunanburh Series and the first two books in the Dark Age Chronicles, my foray to before Saxon England was Saxon England. Enjoy.

The Ninth Century Series (The Last King), are stories of ninth-century England, but not as it's been written before, (featuring an older Icel and some other familiar faces too).

The Erdington Mysteries now has a third book in the series—The Secret Sauce. (Did you know Erdington would have been in Mercia back in the Saxon period? I know, you can't get me away from the place.) The Barrage Body is coming soon.

The Royal Women Who Made England, my first non-fiction book about the royal women of the tenth century, is available now.

I like to write. You've been warned.

4.5/5 (8/10)
First, thank you Netgalley and Boldwood and especially the author for giving me the opportunity to read the 7th book in the Eagle of Mercia series.
I love Icel and its always a real pleasure and comfort to follow him. Well comfort is probably not the right word, cause it gets bloody with him.
The political part was very interesting to me. Usually there is not much insight in the crime and punishment in medieval Britain in these books but the author took a risk here and I personally think, it paied off.
In the beginning, I wasn't sure about it though. I had some problems getting into the book but after around 25% to 30% it got back to Icel's usual shenanigans. From there it was a breeze of blood, betrayal and fights. And as usual, Icel never can catch a break (or some water at least).

Loving MJ Porters writing and hopefully continuing soon with the next book with Icel.

As always, it is excellent to spend some time with Icel as he continues to find trouble and incidents

This time around, the opening third of the book is a trial for the Queen, and rather than the fighting and bloodshed we normally see in this series, it was replaced with politics and a trial. This was a different flavour of writing for the series, and it took some getting used to

It, however, wasn't long until normal service resumed, and Icel was splitting someone from stomach to throat with his weapons. As with every MJ Porter book, she excels in writing battlescenes that feel so realistic you can smell the blood, guts, and gore of a shield wall.

Solid entry for the long-running series

“I’ve been in some terrible positions before, but this really takes the oat biscuit.” Usually we don’t get much humor from Icel but I had to include this little gem. He doesn’t do much cursing anyway, and this just tickles me.

The story centers around some subjects who betray King Wiglaf, and they are very close to the king. We witness a medieval court trial, which I thought would be boring, but I was pleasantly surprised. Just when I thought nothing was going to happen, lots of things happened.
How things get resolved was not very satisfying! But the laws of the day prevailed, and I can appreciate that justice is not always served evenly.
Now events open the door to more intrigue at court and on the battlefield.
There is plenty of messy, muddy and bloody escapades of fighting in the story. Do not fear that it’s all politics. It’s still all very compelling.
Porter has managed to make court trials interesting and entertaining. She throws out twists and turns you don’t see coming. Poor Icel! He barely has time to rest and eat and take a bath! He is constantly on the move.
At least he gets some rest now before the next book.
Another triumph of a story!

It is good to know why Icel is a bit grumpy at times in the Coelwulf series... an outstanding series that answers many questions about Icel's early life, and why he remains with Coelwulf.

Once again, MJ Porter has created a riveting, gritty, nail-biting action thriller from medieval Britain.

This instalment culminates in the trials and subsequent treasonous plots of the perpetrators behind the kidnapping of Lord Cornwulf's children from two books ago and the twists, tension, action, and fast pace do not disappoint.

That said, as much as it pains me to say it, it feels overdo for one of the familiar Mercians to die. It seems Wessex and Saxon warriors die in droves but the same 5 Mercians are always making it out alive. I'm happy about this, as I love Porter's characters, but it does feel a bit plot convenient for everyone to make it to the end alive.

But I digress. This book was fantastic and it did wrap up a bunch of loose plot threads at the end. There are still more to unravel, if another instalment is forthcoming, but if this is Icel's last book, I think it ends satisfactorily.

The author included another note on research for this novel that I found quite fascinating. The author has done an exceptional job in keeping to historical fact throughout this series and it's one of the reasons I've enjoyed it so much. It's truly a gem of a series! I highly recommend this entire series for medieval fiction fans! It really is great!

The 7th instalment in The Eagle of Mercia Chronicles, Betrayal of Mercia, is as rich and vivid as the previous books. MJ Porter can bring the past alive so easily with her storytelling.

Icel has done as he swore he would and protected the children of Ealdorman Conewulf. It is now time to bring the perpetrators to justice. Will justice be served? Or will they manage to evade it as only the wicked can?

As soon as I started reading, I was immediately swept back in time. I do love time travelling from my couch! MJ Porter brings the scenes to life in my head without fail. The battles are depicted as they should be bloody and brutal. The characters feel that real they can spring from the pages. The historical detail always makes me wonder where the fiction stops and the facts begin, It IS that well told!

I was so pleased to return to Icel and discover what was next for him. Again, this is another enthralling and immersive historical novel that I couldn't put down. Thanks to Rachel's Random Resources and Boldwood Books for the gifted ebook to write my honest review.

I enjoyed this rather entertaining novel! Even though large parts of the story depicted bloody battles (I did skip some passages!), it all made sense and did reflect the violence of these times. I found it interesting to see how justice could have been investigated and rendered in a trial . The characterisation was good with a brilliant plot. I really enjoyed it and definitely will read more novels by the author!

This story looks at the King of Wessex, the Queen of Mercia and the survival of the Kingdom.
The agenda of each of the main characters show the betrayal, luck of trust and the motivation of the characters involved. The fact that the main characters need others to assist shows how that the other characters push into the fray to be noticed and provide what matters most.

Having read every title in this thrilling adventure series, I couldn't wait for this one. And, boy, what a cracking read Betrayal of Mercia is!

We are in Londonia – then still split into two halves: the ancient roman Londinium and the later expansion of Lundenwic, on either side of the River Fleet. It was chosen as the place to hold the trial against Queen Cynethryth for treason, and an attempt at murdering Lord Coenwulf's two children – rivals to Cynethryth's son, Wigmund, in the Royal bloodline of Mercia. Their abduction features in earlier novels, and it's well worth reading the series from the beginning, to understand all the individual ambitions. However, this novel reads well as a standalone adventure, as the author has added details of the story so far.

Icel is still recovering from wounds received when he and his fellow warriors captured a woman, Brihthild, who was involved in the conspiracy to abduct Lord Coenwulf’s children. She is to give evidence in a trial many regard with great trepidation.

Early on in Betrayal of Mercia, we read much about Icel's thoughts on the whole sorry mess, which makes for a bit of a slow start. But soon enough, the pace quickens as events chase each other dramatically.

When Cynethryth attempts an attack on Brihthild during the trial, Icel jumps in, and she promptly changes her aim, injuring him before she is apprehended. The queen is confined into a locked cell. And the story takes off from there.

Unexpectedly, the Mercians are faced with a large force of West Saxons, keen to get their hands on Brihthild. A fire breaks out in Lundenwic, and fighting ensues all over the town. Forced to flee, King Wiglaf heads into a forest – with Icel on his heels, keen to protect the king from any marauding groups of West Saxons. But they get lost!

Meanwhile, Queen Cynethryth has her own plans...

Will the Mercians prevail in the face of such a sneaky attack by their West Saxon enemies? And will the queen be brought to justice after all, or will she be able to evade it? And who else is involved in this latest treachery? Plenty of questions for Icel to ponder. Read the novel to find out!

Betrayal of Mercia is a thrilling read, full of medieval political intrigues. And whilst it appears the traitors are obvious, finding proof is an entirely different matter.

The kingdom of Mercia had gone through quite a few changes in preceding decades, where peace never lasts long. MJ Porter knows the era and the characters involved extremely well, and, again, this shows on every page. The research is impeccable, and the setting, battle scenes, the treatment of injuries, and interactions between the characters all appear authentic. As a reader, you do have a strong sense of having entered London in the early Middle Ages.

I love this series, and Betrayal of Mercia is a brilliant addition to it. Fast-paced, with the usual dry sense of humour, some light but appropriate swearing, and with a plethora of scheming characters, who always challenge the status quo.

Icel's character develops nicely, as he is fully aware of his secret birthright – through an earlier Mercian king – but has no intention to share this news with anyone. He values his life as a warrior of Mercia more than a chance at becoming her 'king', and with it the never-ending conflicts.

The ending feels a little final, but I hope we'll see Icel again, as Mercia was never peaceful for long. Surely, there will be another book to keep us so highly entertained and informed on early medieval Mercian politics...

Betrayal of Mercia is another brilliant read by MJ Porter. Highly recommended!

Is this really book 7 in the series already?? So much has happened to Icel yet it feels like only yesterday we met the young boy, supported by his Uncle, trying to find his place in life!

What’s in store next? Well the deadly conspiracy against the children of Ealdorman Coenwulf was uncovered with the help of Icel and now it’s time for those involved to pay the price.. this includes the Queen!!

Mercia has been forced to not only fight enemies from far afield.. but also those close to home and this is a major concern for all those involved.. King Wiglal.. and Mercia want justice..

The Wessex King and his men won’t let this lie though and Mercia is hit with even more betrayal and death as the tale unfolds.

I don’t want to spoil the plot for anyone but let’s just say the case against the Queen isnt as open and shut as the King would like and she still holds some power…and she’s not as helpless as it may seem.

I really found it fascinating to learn of a person’s worth during such instances, and that being in a position of power almost certainly made you trustworthy.. and the words of the common man/woman almost useless unless someone of power would speak of their worth. It really added the depth to that particular section of the story and added an extra umph when we are so used to excitement of battles and blood being the main focus.

Oh and don’t worry the battles are to come as things come to fruition and Wessex make their move.

Character depth and development was spot on as usual. Being on book 7 it’s credit to the author that they manage to keep adding naturally flowing detail into such a pivotal plot. I really love the little tit bits of the past thrown in too, memories on Icel’s uncle, the burning of Icel’s hand for example. These were great little ways for a new reader to be brought into the tale but also exciting for those devoted to the series as we have the chance to reminisce.

MJ Porter has a talent for historical fiction and this ever clearer when you see the shear amount of characters involved in the tale, which must have taken meticulous planning to not mix up names at pivotal points. I love Porter’s style too, I’ll be the first to admit names can be hard to retain in novels such as this are they aren’t names used in todays world.. but Porter manages to introduce what feels like natural pause points when the reader can reflect, and really absorb what is being told.

I’ve never really liked King Wiglaf but in this instalment It really showed him in a different light… the question is will he figure out who Icel really is and his family links? The King is kind to him now but if he see’s him as a threat to the throne will he be so kind?

How long can Icel hide the truth…

Without spoiling things I can honestly say this instalment is the best yet, flow is effortlessly perfect and the plot excruciatingly riveting.. I’m just glad I have the commute to work to enjoy the tale as I didn’t want to put this one down!

Betrayal of Mercia is the seventh book in The Eagles of Mercia series by MJ Porter. In this installment, we find Icel nervously waiting to testify in the conspiracy to kidnap the royal children, and the queen is on trial. ‘Brihthild of Wessex’ is supposed to speak against her, but despite everything the Mercy in Warriors went through getting her to Ladonia. She doesn’t deliver at least not until the queen goes to testify. This is when the queen tries to attack her, but instead gets poor Icel in the face. Once they lock the queen away with Eric and the other king’s guards standing as sentinels, things only get much worse, and they find Wessex Warriors on the shore, and to make matters worse, they want to free the queen. Even King Wiglyft goes to fight, and soon Icel is lost in the woods with the king, but this is just the beginning of the nightmare. It seems everything that can go wrong does go wrong from the queen getting away to other battles. They’ll have to fight so as not to lose Mercia to the king of Wessex. They get long-lost visitors that return. Icel finds himself risking his life to save the last person he ever thought he would. This series and especially this book is like the gift that keeps on giving; it has twist after twist after twist, and I was there for all of it. I love this series and think the author does such a phenomenal job, not only pushing the story along but making it exciting, pulse-pounding, and a real page-turner. If you love historical battles with a real, engaging plot and an exciting narrative, then you definitely need to read the Eagles of Mercia series.! there is so much I love about this series. It would take me pages upon pages to say everything that brings me back, wanting to continue the collection, and I couldn’t recommend it enough.#NetGalley, #BoldWoodBooks, #MJPorter, #BetrayalOfMercia, #TheEagleOfMerciaSeries

M J Porter’s Chronicles of Mercia series keeps getting better and better and Betrayal of Mercia is another action-packed historically rich page-turner readers will not want to miss.

The perpetrators behind the deadly conspiracy against the children of Ealdorman Conewulf have been unmasked and the time has come for them to face justice. But will they get what is coming to them? Or will dangerous forces ensure that they do not pay the harshest price of all for their shocking transgressions? With his wife implicated in the plot, King Wiglaf’s position looks set to become untenable and with his enemies circling round, it looks like the truth behind the conspiracy will continue to remain hidden.

With Mercia reeling from this monumental betrayal, the King of Wessex’s son, has turned his attention to this land. Nothing and nobody will prevent King Æthelwulf from his dearest wish to end Mercia’s ruling bloodline once and for all. With Mercia about to be invaded yet again, will Icel and his fellow warriors triumph? Or will adversaries hiding in plain sight end up destroying this once great land once and for all?

M J Porter never fails to make history come alive and with Betrayal of Mercia, this talented storyteller has once again penned an exciting, fascinating and enthralling historical adventure that takes readers on an unforgettable journey to the past they will not forget in a hurry. An enjoyable and entertaining historical novel readers will not want to put down, Betrayal of Mercia is another triumph for M J Porter.

This historical fiction novel immerses readers in the treachery and intrigue of King Wiglaf's court, where betrayal strikes uncomfortably close to home. The story unfolds with a riveting medieval court trial that surprises with its unexpected twists and gripping developments. While the resolution may not be satisfying, it accurately reflects the harsh realities of the period’s justice system.

Porter masterfully balances courtroom drama with the brutal realities of medieval warfare, delivering vivid, action-packed battle scenes that are as captivating as the political maneuvers. Each moment, whether in court or on the battlefield, is brimming with suspense and unexpected turns, keeping readers hooked throughout.

This book offers a richly detailed and engaging portrayal of an era filled with secrets, danger, and relentless intrigue. It’s a must-read for fans of historical drama, and it leaves you eager to dive into the rest of the series!

My thanks to the Author publisher's and NetGalley for providing me with a Kindle version of this book to read and honestly review.
Another excellent edition to this superb series completely recommended, though the beginning and ending had me thinking I had started a John Grisham book by mistake, as we were in court even the Author in his notes claimed surprise at it. As usual our hero Icel managed to find himself in the centre of the action. I have read a number of books by renowned Author's of this genre, and been in a few shield walls, but this one was special, you felt a part of the action, the agony atmosphere gore smell and tension.
AMAZING.
I am already looking forward to the next story, or maybe I should catch up on a couple still in my To Be Read pile first.
Completely and totally recommended.

After a conspiracy to kill the young heirs to Mercia is foiled, Icel finds himself in Lundenwic for the trial. The Queen is accused but she manages to break free and try to escape to the other side of the thames where the lords of Wessex await her. After much fighting he depths of the conspiracy will be revealed and this has implications for the succession.
I do like Porter's historical novels and, even though this is the seventh in a series, I found it relatively easy to pick up on the plot. The action scenes are suitably grim and bloody, the politics complex and the descriptions of Anglo-Saxon life both historically accurate and well-imagined.

Icel saved the children he was sworn to protect and now he has presented the evidence discovered that implicates the Queen. She will now stand trial. The King must remain impartial but she will confess nothing and even tries to kill the witness against her.

Well written, action packed, well paced novel. Strong characters, many we have known in previous books. Will justice be served on the Queen and those who aided her and how many battles are yet to be fought?

It took me awhile to get this book read. Although I love the subject matter of Anglo-Saxon England the story was a bit dry. The characters were amazing, especially Lord Icel and his cohorts but some of the describing of the situations was repetitive. To have a series in favor of Mercia instead of the more written about Wessex is a boon.

Another fantastic read

I love this series and really enjoyed this addition to it. Well written and fast paced, I read it over a weekend as I just had to keep reading to find out what happened. Icel is such a great character as are his friends and allies and his story is always interesting, it’s great to follow him as he grows and learns and can’t wait for the next book!

Pace

M.J. Porter’s books are always filled with battles. The pace is fast, the hero’s are epic, and honor is always satisfied. Which is probably why I own almost all of them. Good reads particularly if you like inventive fighting.

I believe this is the first book that I am reading by this author and I was not disappointed. I enjoy books with battle scenes, and it does feel like I'm along for the ride. It's probably not the best way to describe it, but it gives the story more details to the world building and to the characters. The characters in the book were very well depicted and truly brought this entire world to life. You really get a feel of the era you're reading about. It was not a time you wish to be a part of, especially when there's a ton of secrets being kept. It was interesting to read on how investigations were being held during this time. Some parts were constantly repetitive, but that's okay. It didn't bother me so much. It doesn't take away from how good this book is. I will absolutely be reading more from this author.
