I was sold on this book before I knew it. It was hard for me to put down for even a minute! Extremely fast-paced, this book has a lot of action and suspense set in a fantasy world where the Great Library of Alexandria had never been destroyed. A world where the library has quite a bit of power. Unfortunately, like with most things that have power, there is also corruption. And where there is corruption, there are those that fight it. A definite recommendation for any teen or adult who has a love of books.
