        Mr. Lemoncello is a madman (or genius, all a matter of opinion) that creates games and technology. After a library is opened in his town, Kyle Keeley decides he just has to win the essay contest to get into the special opening night - because Mr. Lemoncello will be there. Only problem is, he hasn't written his essay....and when he does, it is only a couple of words: "There will be balloons." After he is mysteriously admitted into the sleepover, it turns out to be something else entirely-a new game! In a race against time, Kyle unites with his friends to go against Charles Chiltington, who claims to always win. Kyle learns the meaning of friendship and how great libraries are. I would TOTALLY recommend reading this book, it's easy, fun-filled, and an imagination jackpot. Great for all ages! -BKS

              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.
