This book is magical, you will get lost in a world where the "not normal" is suddenly normal. The characters have to find their way out of Mr. Lemonchellos library for a prize. I have read this book multiple times because I have enjoyed it so much. The 2nd and 3rd books (Mr. Lemonchellos Library Olympics, and The Island of Dr. Libris.) are amazing! They all have a small part of all the other books in them.
Alan Gratz has his writing figured out with this book. Personally I didnt like Prisoner B-3087, but this one is amazing! There is a perfect amount of suspense and dialogue that you wont want to put the book down!
