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

      I got this for Easter 2 years ago, and pushed it off until the very end of this summer. I'm mad that I did, because it was such a good book. There is a second one, but I can't remember it's name off the top of my head.

        I read this and it is very mysterious and you want to know more. If you like mysteries, this is the perfect book for you. Kyle suddenly realizes that he is chosen to be invited to the opening of the new library. He then gets himself into the game that the new librarian decided that she would experiment on them. Will Kyle be able to win the game or will it involve a bit of teamwork?

              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.

                      This book was amazing! it is one of those books that I could not put down. It captures the picture of a gameshow I would love to see and be on. I love how team Kyle worked like a team and there was not one person in that group who wanted the prize just for themeselves. I love how this book wasn't too stressful. There was some suspense if they might not get a awnser right. I love this book. I give it a 5 star rating. If you happen to be at the library or bookstore please check this book out.
