The Invisible Library Book Review



Title: The Invisible Library

Author: Genevieve Cogman

Blurb (GR): The first installment of an adventure featuring stolen books, secret agents and forbidden societies – think Doctor Who with librarian spies!

Irene must be at the top of her game or she’ll be off the case – permanently…

Irene is a professional spy for the mysterious Library, which harvests fiction from different realities. And along with her enigmatic assistant Kai, she’s posted to an alternative London. Their mission – to retrieve a dangerous book. But when they arrive, it’s already been stolen. London’s underground factions seem prepared to fight to the very death to find her book.

Adding to the jeopardy, this world is chaos-infested – the laws of nature bent to allow supernatural creatures and unpredictable magic. Irene’s new assistant is also hiding secrets of his own.

Soon, she’s up to her eyebrows in a heady mix of danger, clues and secret societies. Yet failure is not an option – the nature of reality itself is at stake.

Thrilling, and so action packed from the first page, The Invisible Library draws you in from the front page, and takes into a whole new world filled with… TIME TRAVELING LIBRARIANS! I enjoyed this book so much! I’m ready for book 2! 


  • Plot – The most thing I enjoyed about this book was its plot. Irene is a Librarian, but not your average librarian. She works for the Library, a secret society (how cool is that) that uses magic to recover books (important books) from different time periods. Irene’s mission is too retrieve a book filled with vital information, with a junior named Kai. However, the book is stolen by a cat burglar, and the owner is dead. Irene, Kai, and with the help of a private detective go on journey to find the book. I didn’t explain it’s awesomeness well enough, #sorrynotsorry. The plot had a lot of plot twists, and at some point could be very random (like cyborg alligators, and giant centipedes), but it was fun, and it kept you interested.
  • Characters – I loved all of the characters in this novel. They weren’t weak, but had these strong personalities. Kai and his innocents just made him even more lovable. Irene toughness, and her uncanny ability to stay calm during a crisis, was a little annoying at first, but it came in handy, and then admirable.
  • Setting –  The setting takes place in an alternate world in 20th century London with a paranormal twist. I usually don’t talk about settings in reviews, but this one added more fun to the novel.
  • Writing Style – The writing style was phenomenal, and added so much class to the book.


I cannot think of anything wrong with this book! It was great.



I was sent a copy from the publisher for a honest review


I rarely give 5 stars to books, but this book deserved it!

      1. She has an amazing story and I am excited to see where it goes. I really need to finish this book like THIS WEEK! I have another book that I borrowed that someone needs back that I am trying to plow through in the next three day though.
