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


Starred Review, Booklist

            I loved this book. If you like logic games, non-fiction, and The Candymakers or Charlie and the Chocolate factory.

              This was a fun read, full of gaming, friendship and courage to be a friend when others are choosing to not. I wish I could solve the mystery!
