Is there anything cooler than time-traveling, dimension-jumping, librarian spies? Plus, dragons and fae! And the fate of worlds lies in the balance. Yes, that is worlds plural. The next installment of Genevieve Cogman’s Invisible Library series, The Mortal Word, checks all the boxes and is releasing on November 27th.

The Mortal Word continues the adventures of Irene Winters, a dedicated Librarian, and her friends. The Invisible Library is a wonderful magical place in between a myriad of different worlds, each living under different levels of order or chaos. In this series, Dragons are beings of order and Fae are beings of chaos. And the Library and the Librarians try to maintain a balance of order as best they can by stealing books! Have I intrigued your interest yet? If you’re a fan of varying adventures of Doctor Who, you’re probably going to enjoy The Invisible Library series.

The upcoming installment faces that balance or order and chaos head-on. A murder threatens to create even more upheaval throughout the entire universe. Irene Winters, along with her friend Vale a renowned detective in his own home world (akin to a Sherlock Holmes but with less sociopathy).

The Motral Word begins with adventure and does not let up. The pace is quick and the prose entertaining. You are constantly drawn into the murder-mystery but faced with larger conspiracies entwined with “normal” problems of anarchists in a metropolitan area. With every book in the series, Genevieve Cogman continues to build the world and allow you to learn more about Irene. Irene is a brilliant, beautiful, intelligent woman who plunges into an adventure, sometimes unwisely.

“My life is painfully full of learning experiences where I’ve had to be an expert at short notice.”

But she is aware and learning how and when to allow her friends to help or lead the way. The continued growth of Irene, her no-longer apprentice, dragon prince-ling Kai, and Detective Vale make The Mortal Word another entertaining sage in the Invisible Library. One that you need to read to find out whether order or chaos reigns.

The latest in the series, The Mortal Word releases on November 27, 2018 from Ace Trade Paperback.

About The Mortal Word

In the latest novel in Genevieve Cogman’s historical fantasy series, the fate of worlds lies in the balance. When a dragon is murdered at a peace conference, time-travelling Librarian spy Irene must solve the case to keep the balance between order, chaos…and the Library.

When Irene returns to London after a relatively straightforward book theft in Germany, Bradamant informs her that there is a top secret dragon-Fae peace conference in progress that the Library is mediating, and that the second-in-command dragon has been stabbed to death. Tasked with solving the case, Vale and Irene immediately go to 1890s Paris to start their investigation.

Once they arrive, they find evidence suggesting that the murder victim might have uncovered proof of treachery by one or more Librarians. But to ensure the peace of the conference, some Librarians are being held as hostages in the dragon and Fae courts. To save the captives, including her parents, Irene must get to the bottom of this murder–but was it a dragon, a Fae, or even a Librarian who committed the crime?
