Charlie and the Chocolate Factory meets A Night in the Museum in this action-packed New York Times Bestseller from Chris Grabenstein, coauthor of I Funny, Treasure Hunters and other bestselling series with James Patterson!

Kyle Keeley is the class clown and a huge fan of all games—board games, word games, and particularly video games. His hero, Luigi Lemoncello, the most notorious and creative gamemaker in the world, just so happens to be the genius behind the construction of the new town library. Lucky Kyle wins a coveted spot as one of twelve kids invited for an overnight sleepover in the library, hosted by Mr. Lemoncello and riddled with lots and lots of games. But when morning comes, the doors stay locked. Kyle and the other kids must solve every clue and figure out every secret puzzle to find the hidden escape route!

Don't miss the next puzzle-packed adventure—Mr. Lemoncello's Library Olympics—coming in January 2016!

"Discover the coolest library in the world." —James Patterson, #1 New York Timesbestselling author

      This was an amazing book! I just loved to sit write down and read it. There are some words, like stupid or loser that are mentioned in this book, but overall it is a great book. I love the library!

        This book is amazing!! I love how it is a library but it is also a magical place! It is kind of cool how they have to solve puzzles to get out! You should definitely read this book and the other books in the series.

            This was such a good book! I really wish my library was like the one in the book! :) It was so thrilling, yet added many aspects of everyday life. I highly recommend this to all readers out there!

              Kyle is a huge fan of Mr. Lemoncello and of all things games and puzzles. He is thrilled when he is chosen as one of the twelve kids chosen to get to sleepover in the brand new library that Mr. Lemoncello built. Secret puzzles and games that lead to a hidden escape route (with a prize!) await. This was a really fun book that I would recommend to elementary grade and up. I rate this book 4 out of 5 stars.

                  This is a really good book. I read it more than once and I really recommend this book. The second time I read it was after watching the movie. The book is way better than the movie.

                    Escape from Mr. Lemoncello's Library is an amazing book. These kids have to play this game-to escape from the library. They must solve all sorts of riddles and team up in order to be the ones to escape. The colorful characters, funny humor and tense pressure makes this book a must read.

                      I liked Mr. Lemoncello's Library because it contains lots of riddles and puzzles to solve. There is a rivalry between the two main characters, Kyle Keeley and Charles Chillington. Kyle plays by the rules and is fair, but Charles turns out to be a bully and cheats all the time. There is a lot of suspense and twists and turns in the competition to see who can figure out how to get out of this high tech library.
