Ms. Mahoney epitomizes the ideal conclusion to a trilogy with The Stone Demon. Thankfully void of loose ends, neither was each and every situation systematically closed out, as if checking off a list. Admittedly, some resolutions and explanations are needed; and answers were provided in a very satisfactory way, with any remaining questions providing excellent points to ponder long after the story has been told.

The first book, The Iron Witch, introduces Donna Underwood who wants nothing more than

Quests are usually long-winded things. Heroes tend to find them difficult, often taking months, years; some pursue theirs for a lifetime.

Donna Underwood usually completes hers in 2 days or less.

It took me two books to figure this out, it was so well hidden, but I've figured out that Donna is a Mary Sue. It skipped over my mind because of the lack of emphasis on appearance that the author places on Donna, but when other things are put into consideration, that's what she is.

-Meh, it wasn't bad but it certainly wasn't good. I was bored through most of the book… Nothing interesting really happened, I found most of the characters dull — bar Navin and that statue demon who were rather entertaining.

-Anyway, Donna (the heroine) is with the Order (a secret society of alchemists that Donna is a part of) in London as punishment for unintentionally opening a portal/door between the demon realm and human realm.

The Stone Demon is the third and final book in the Iron Witch trilogy so this review may contain spoilers for the first two books. The story picks up not long after the end if the last book and there is very little recapping so I really would recommend reading this series in order. Donna has been sent to London as a punishment for freeing the Demon King and his minions and is now continuing her training with the Order of the Crow. The Demon King has demanded that the alchemists hand ove

I always feel nervous when I come to the final book in a trilogy that I love – will it live up to the first books in the series? Will the characters that I've grown to love get the happy ending that they deserve?

Luckily, in The Stone Demon – the final book in the Iron Witch trilogy – Karen Mahoney does not disappoint. Donna is the feisty heroine of the trilogy, a member of the mysterious Order of the Dragon sect of alchemists, whose power is magically bound b

I really did enjoy reading this series. I loved the storyline and the character of Nav was my absolute favorite.
But what I liked most is that - THIS WAS NOT A TEENAGE LOVE STORY! Not really, not like Ash & Megan, Clary & Jace... It's a story about a young girl (Donna) who was born with an amazing gift, trying to live her life while working her way through a world full of secrets & lies & people who see her more as a weapon then an actual human being.

I gave up. I didn't even finish this book. It was soooo slow and frankly Donna's inner monologue was tedious. I just skipped to the end to see what happened. Not surprised about Xan's father; the clues were there as soon as he appeared on the page. Was I supposed to be surprised? Losing the last bits of the elixir of life and opening a door to the demon world on the advice of a KNOWN ENEMY is just ridiculous. After all the idiotic things Donna does, I'm amazed that she doesn't get more suitably ...more

I can not wait for this book to come out. Hopefully there will be more Donna and Xan! The last book didn't exactly end on a cliff hanger but close enough for me. I think Donna's power will unfold even more.

After being tricked by Aliette into opening the door for the demons to return to Earth, Donna has two days to create the philospher's stone the demon king is demanding or else he'll destroy London and her home town. Donna is pretty much on her own since the alchemist's have said it is an impossible challenge and are gathering forces to fight a war with the demons.

Donna does have some allies. Her best friend Navin may only be a "commoner" but he is smart and loyal. Xan may be busy working with Ma

After the shocking blow of the previous installment, Donna Underworld was left scrambling to find a way to close the doorway that allowed the demons to escape their realm. But then the Demon King issues an ultimatum, deliver the Philosopher's Stone or humanity will perish in two days time. Problem is that no one remembers how to fully create the stone. Faced with an impossible task, Donna will have to use every bit of strength and ingenuity

The Stone Demon wraps up the Iron Witch series in such a way that will leave people either loving the story, or totally wanting to pull their hair out of their head in frustration and agony. When we first open the pages to The Stone Demon, Donna Underwood, aka the Iron Witch, is understandably angry at herself and depressed after allowing Aliette, the Wood Queen, to talk her into opening the gates of Hell and allowing the demon king Demian to re-enter the

I have really enjoyed this series from the beginning, so after following Donna on her journey as she learns about herself and discovers the truth behind her iron tattoos I am sad to see it come to an end. Donna is in London, England training to be an alchemist, having been sent there for releasing Demain, who is now causing havoc, most notably burning down the British Museum.

The Stone Demon also gives us points of view from Xan and Navin, whose I love the most thanks to his sense of humour and c

Ah, the Twilight-era of YA, when you couldn’t move in a bookstore without seeing a paranormal love triangle. Sure, some great books were released during the period, and it’s fun to revisit it from time to time largely for nostalgic purposes, but most of them just feel like they lack heart, and sincerity, especially compared to the quality of YA today.

This trilogy definitely falls into the ‘nostalgic but forgettable’ category for me. Am I going to remember this trilogy in a few years tim

Yet another series comes to an end. So many series I like ended this year. Guess they all have to end at some point. This is the 3rd and final book in this series. The first book was The Iron Witch, the second was The Wood Queen, in case you’re unfamiliar with it. It’s full of alchemy, faeries, elves and demons. The main character Donna is definitely a strong protagonist. My favorite character is Nav, because he’s the funny best guy-friend. The love interest is still Xan, the half-fey guy, but I ...more

Please bear in mind that this is the third and final book in the series and the review may therefore contain spoilers for the previous books.

The story picks up with Donna now in London shortly after the ending of The Wood Queen here is very little in the way of recapping, this is definitely a series that need a to be read in order to fully understand the complexity of the plot.

Mild Spoiler Alert!!

I am not overly fond of this book. I loved the first two but the ending was just to off for me.
Karen had these moments towards the middle and end that just seemed to unbelievable even for a fantasy novel. There was the instance when the Wood Queen just gave Donna her artifact. Her only price was to make sure Simon died. Then there was the whole trip to underworld thing that I just didn't get.

Karen Mahoney's "The Stone Demon" is the third and final book to "The Iron Witch" trilogy, and I think its content is more on the level with the first, though with a few caveats to consider. I appreciated the journey with the familiar characters and imaginative settings, with nods to fae lore. It started off a little rough in the beginning with pacing, but as the novel went on, it improved with the stakes and immersion since there were multiple players in the story tasked with doing different th ...more

I was sent a copy via NetGalley in exchange for an honest review.

In the third and final book of the Iron Witch Trilogy, Donna is now in London, not long after Wood Queen has ended, and with the demons released. The Demon's set the Order Of The Crow the task of delivering the Philosopher's Stone. Donna has to recreate the Stone before the world is put into a Dark Age.

For anyone thinking of reading this book, I feel it important to point out that it is the third and final book in the series, and
I thought this book was better than the first two in the trilogy although it still wasn't amazing. This book starts where the last one left off, Donna has been sent to London as part of her punishment for releasing the demons. Donna is invited to a ball by the Demon King and he wants her to recreate the Philosopher's Stone which will involve collecting 5 ingredients. This leads Donna on a quest in order to get the ingredients and save the world from being destroyed.

I enjoyed this series. I don’t know if it will be a reread for me but I would recommend it to YA novel readers.

The overarching plot that is seen over the course of the series is finally resolved. In my opinion, it’s not completely satisfactory in the ending, but it works. It gives enough of an explanation that I will accept it.

The character development was kind of slow throughout the series. A l

Because this is the last book in the series I was practically dreading reading it because I HATE it when authors don't finish them to my liking. Because if something goes wrong it will never be able to be resolved and I hate that thought. But one thing that I did like about this novel was that she did tie up most of the loose ends pretty nicely (except for one) and made sure that every character had their own little story told to us at the end.

The first thing, tht got my attention on Karen Mahoney's The Iron Witch series was the cover! Since the first book, i loved the covers! So beautiful!! But of course, the story is pretty cool!!! I loved the way she blended fair folk, otherworld and alchemists. It was very creative! I confess, i didnt like Navin. His humor annoys me! But he is a nice friend! Always ready to help Donna!
