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 is such a wonderful story. It is filled with puzzles, books, and games. It is one of the best books I have ever read. Kyle and 11 other kids are chosen to do an escape from the library game. It is extremely funny and educating. I definitely recommend it.

      This is such a creative book! I think the idea of it, how it's an escape/mystery book, is really cool. I like mystery books, but most of them are sort of creepy, so I think that that makes this book sort of unique. I would recommend it.
