Summary (from http://www.goodreads.com):
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.
Oh my goodness! How wonderfully fun was this book?! Another recommendation from a fellow bibliophile, this was an addictive read.
Irene is a spunky, resourceful, professional spy who collects books for the mysterious Library. I enjoyed Irene’s asides (written in parenthesis) and the humour with which Cogman voices her. Kai, Irene’s apprentice, is powerful and enchanting and a trusted colleague. The interaction between Kai and Irene is, for a lack of a better word, fun to read.
I can’t say enough about how much I enjoyed this book. The mix of magic and mystery and adventure and a strong female lead has made this one of my favorite reads of this year (well, in the last two weeks!). I’m already on to the second book, The Masked Library (The Invisible Library #2)!
