"We want books. We love books. We live with books."

Irene is a professional spy for a mysterious Library. She is sent on a mission to an alternative London with her colleague, Kai, to retrieve a dangerous book. They get there to find the book already stolen in a chaos-infested world (one where supernatural creatures live and unpredictable magic occur), making their mission even more difficult.

I am always so intrigued when it comes to reading fantasy. Learning about a new magic system, following new lingo, becoming familiar with different characters, parallel universes. Also, a mysterious Library that no one knows about??? A book about books is always wonderful!

I really liked the characters and how their relationships formed. Irene was thrown into a dangerous mission while becoming a mentor to someone she's never met, Kai. Even the rivalry between Librarians, and facing villains in an alternate universe made the mission even more interesting. 

As much as I enjoyed the book, there were a lot of confusing parts as some things weren't thoroughly explained and I had a lot of questions. It's not a big problem imo though because an introduction into a series usually has a lot of info that will eventually come together if you continue on. This is book 1 in a series of 8. I liked it enough that I plan on continuing the series to see how it all pans out.
