A corrupt countess
A spy in danger
And an assassin at large

The fifth title in Genevieve Cogman's witty and wonderful Invisible Library series, The Mortal Word is a rollicking literary adventure.

Peace talks are always tricky, especially when a key diplomat gets stabbed. This rudely interrupts a top-secret summit between the warring dragons and Fae. As a neutral party, Librari

Any time a new book in this series is announced, there should be an international holiday of celebration and reading. What a treat.

Fans of Investigator Vale will be happy to know that he is back and center-stage. When an assassination takes place at a fae-dragon peace conference, he is the natural choice to find the killer. However, there are political considerations involved, and he is given a team of one librarian, one fae, and one dragon work together. Irene is, of course, the assigned librar

I look forward to every book in this series and have not been disappointed yet! I love the idea of a library between worlds and magic doors which open to different libraries in different places and times. Plus the most important characters are a librarian and a dragon. What more could you ask for?

After five books it was time that Irene and Kai actually got it together even though most of the action was left to the reader's imagination ( that's okay - we have plenty!). The whole book was action p
Thanks to Netgalley and the publisher for offering me an advanced copy in exchange for nothing more than an honest review.

If you haven't picked up The Invisible Library, stop reading RIGHT NOW and go pick it up. It's a clever world of time-travel-adjacent adventures with dragons and fae and even a magic language of sorts. It's like Doctor Who meets The Chronicles of St. Mary's, and it's a BLAST to read. So go pick it up. This one is book five, so reading any more now will just spoil all your fun

I NEED this book. Love this series so freaking much it hurts, y'all. It. Hurts.

(Please go read the first 4 books so you can feel my pain and join me in the wait for book #5!)

I really wanted to like this one more. I liked it well enough but to be honest it was rather bland. it was so bland that a week later I still have no real opinion on it. I remember the main points but everything else is a blur which makes it a mediocre book in my opinion at best. Still I liked the path the series is taking and hopefully I will still care enough to pick up the next book when it's published.

THE MORTAL WORD is the fifth book in The Invisible Library series. I've read every single book in the series and I could not wait to read this book. Irene's job is to steal rare books from different worlds for the Invisible Library. She loves her job, the adventures, the books. After a job in Germany, Irene learns about a secret Dragon-Foe peace conference that the Library is overseeing. But when a high- ranking Dragon is murdered, the peace talks come to a halt. Irene and her friend, private d ...more

This was another great installment in the Invisible Library series. I have really enjoyed all of the previous books in this series so I was really excited to read this new installment. This is the fifth book in the series and I do think that this is a series that is best read in order. I had a great time jumping back into this complex set of worlds and thought that the story was very well done.

If there’s one thing I can say about The Invisible Library series, it’s that I can count on the books being consistently solid and entertaining. That’s why I always look forward to picking up the next installment, and that was most definitely the case too with The Mortal Word.

In this fifth volume of the series, the war between the Fae and Dragon-kind is heating up. Attempts to broker a peace treaty are jeopardized when a h

Why am I so Meh about this series?


There are a lot of things that I like about this series.
-Irene, Vale and Kia are all pretty likable characters who have a decent number of flaws to make them interesting

- The various worlds with different levels of order and chaos we travel to are also interesting.

- I idea of the library and it’s ambiguous involvement in each book’s crisis. I still have no idea if it is a mostly good or bad place.

- Each individual book plot. They are all different and episodic

Being away from this world for so long, did make it hard to jump back in. I had to find the groove of it again, but once I did I had a fantastic time. It has a good mystery to it with a conclusion I honestly did not see coming.
We of course have more mentions of our big bad (is he gone or isn't he?) and the romance does move forward, but it isn't highlighted, as usual.

This world and the characters really are the best at sweeping me away to different worlds. I'm really excited for the next books

Another adventure with Irene, Kai, and Vale? Yes, please!! I was extremely excited to receive this ARC ebook from the publisher. I hate waiting for Invisible Library novels from the library because the queue is always long, and for good reason— they are full of action and adventure.

Our favorite series characters are assembled to investigate the murder of a dragon advisor during peace negotiations between the dragons and fae. If you haven’t tried this series yet, you are missing out. I can’t wai

The Invisible Library series is one of the most imaginative series in existence at the moment  – especially for those of us who are absolute book addicts-  it’s a heady mix of Literary adventures, magic, multiple worlds and books that hold the universe together. There’s dragon’s too. Just saying. Oh and Fae, must not forget them. Well unless they want you to of course…

Irene is a librarian, a spy, a kind of thief if you like and quite often saves the world(s)…

Review copy was received from NetGalley. This does not affect my opinion of the book or the content of my review.

I've been reading and enjoying   The Invisible Library series  since the beginning.  The world-building is almost a fresh start in each book since Irene travels.  She has been assigned a home world where she lives and has some regular friends and frenemies. There are a few Library characters who are around throughout the series.
I was so excited when I got approved for the ARC of this book, especially because I was rejected same time last year for The Lost Plot and it felt like an affirmation that I’m now a capable blogger 😉😉😉 And I’m so glad to have read this book because it has all the wonderful elements that I have loved in the series with an extra dose of politics that I really enjoyed.

Irene is such a strong female character that I’m surprised she is not talked about more in the book community. She fights with the t

In this version of the multiverse the Library serves to provide the balance between the fae worlds of chaos and the dragon worlds of order. Humans don’t do well at either extreme, and it’s the Library’s function to guard and preserve the middle ground where human beings thrive.

Just because the Library serves as a point of balance does not mean that the lives of any of the Librarians that serve it are remotely balanced in any way. It could be said that the L

While each book contains a clever, suspenseful mystery this series is best read in the order of its release. Complex story arcs, relationships and incredible world building are built upon in each title.

A couple of things you need to know. Worlds ruled by or where Dragons dwell tend to be filled with order. As one would expect worlds where the Fae live or dwell tend to be filled with chaos. The Librarians collect books that are dangerous or need protection to keep the balance between order and ch
The Mortal Word is the fifth installment in Genevieve Cogman's delightful Invisible Library series, which follows the adventures of Irene Winters. As an agent of the Library that exists outside of space and time, Irene travels to various alternate worlds and collects (okay, steals) books to add to their reserves.

Though the first chapter and the last 80 pages or so are quite engaging, I think The Mortal Word is the weakest installment in the series so far. It has some fun parts, but the middle fo

Another fantastic instalment of one of my favourite series. Can't wait for the next adventure for Irene, Kai and Vale 😍😍😍

This series is so fun! The author manages to keep it fresh and exciting, with an ever expanding world(s). I’m not at all biased because the main character is a librarian. Really, I’m not.

I received a free netgalley from the publisher. I am in no way obligated to provide a review. My review is completely unbiased.
I was very pleased to have received an advanced copy and happy to report Cogman has delivered another awesome fun fantasy with Irene and company. This time Vale is called upon to use his super sleuthing skills to assist Irene in solving a murder that has occurred at Peace Talks taking place between the Dragons and the Fae.
My favorite thing about the book is Irene. She
I love the Invisible Library series so much. Such a unique universe! I enjoyed how The Mortal Word was more of a "traditional" detective novel than previous books, but have a serious bone to pick about the fade to black between Irene and a certain handsome someone.

This is an incredibly enjoyable read that's full of twists, political intrigue, magic, and the complex world and character-building that Cogman has perfected. It's a mystery wrapped up in a historical outfit with dashes of magic and action. It's a mix that's hard to ignore.
The signing of a peace treaty between the ever-warring factions of Chaos (Fae) and Order (Dragons) is in the hands of a neutral party (the Library), but the murder of a dragon endangers things and Irene, Vale, Kai, Silver, an

Review courtesy of All Things Urban Fantasy.

THE MORTAL WORD, the fifth installment in the Invisible Library series, is as delightful as the rest of the series. Mixing fantasy with historical locales with a murder mystery continues to be a successful combination of elements to showcase Cogman's character development and wit.

As I've mentioned before, Irene is one of my favorite fantasy characters, for a number of reasons. However, I've come to realize that a lot of how I feel is based on how other

"Was she the library's agent, or the Princess' knight? The Cardinal's spy and assassin, or the Countess' victim? Kai's lover? Vale's friend? Where did she ultimately stand in all this?" Genevieve Cogman, The Mortal Word, page 264

It's that time of year again. The time when I gush about The Invisible Library series for a whole post and you all have to sit there and take it.

Well. Unless you close the tab, I suppose.

The first time I read an Invisible Library novel I enjoyed the first book, but bounced off the second. It took me a while to come back to the series, but when book #5, The Mortal Word was given to me to review, I was able to dive into book 2 again and absolutely binged books 2-5. The first book had a serious issue with clunky world-building as info-dumps, and the rest of the books still suffer from the same issues, but to a lesser degree.

This series is supposedly about Irene, but her world’s unp
