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 detective Vale, are ordered to go to 1890s Paris and investigate the murder and find out who killed the dragon, and why?

The Invisible Library series is such an awesome series. How can you not enjoy reading books about a library that collects rare books from different dimensions? The previous book, BOOK, was not my favorite, but I'm happy to say that THE MORTAL WORD was a wonderful read. I enjoyed having Vale back in the game! If you like Sherlock Holmes, then you will like Vale. And, Irene, as always, is a fabulous character. She's always in trouble, but through it all, she finds a way to solve the mystery, save the Library's reputation, and on top of all of that, save her parents' lives!

THE MORTAL WORD is one of the strongest books in the series and I can't wait for the next book to be published!
