        Mr. Lemoncello, also a game maker billionaire, grew up in a town in Ohio, but the library he loved as a kid isn't there when he comes back. he builds a new, modern library and holds a contest for the 7th graders at the school in town to write an essay. The winners get to stay the night and play a game, or a puzzle to escape from the library without the front doors, but with clues.

              Hello readers, I just finished reading Escape From Mr.Lemonchellos Library by Chris Grabenstein. This book is a futuristic realistic-ficton book. It is for ages 6 and 1/3 and up. It is about a kid who loves to play Mr.Lemonchellos games like everybody else because he is famous. One day kyle heard about a new library coming out that has holograms and many other awesome stuff. Twelve students who do the best essays get to be the first in the library and get to sleep over there and Kyle is one of the students. Later at the library they here whoever can get out of the library first without using the fire exits or main door gets to be Famous with Mr.Lemonchello! It is a race between the 12 students to see WHO WILL BE THE WINNER!! This book is very exiting because in the book there are many challenges and cool rooms for the students. You should defiantly read this book! I recommend it and give it 5 out of 5 stars! P.S this book is not only for kids who love reading, it is also for kids who like electronics because there is video cameras, holograms and more in this book! Hope you like it!

                The beginning of this book seems to be boring but in the middle it really started to grab my attention. I personnally love puzzeles and adventures. This book gives me exactly what I love. It also reminds me of the movie 'A night in the museum'.

                    Your going to want to hear this review and then read this book. The book I read was called "Mr.lemoncello's LIBRARY" it is by Chris Grabentein, and it is great. The settings of this book are the library and sometimes the school. The library is the most common place. So this kid named Kyle Keeley loved Mr.lemoncello's games and books so he decided he wanted to enter a contest to win a trip to his library. What you have to do to win is write an essay so that's what Kyle did. When the winners were announced Kyle ended up being one of them. What he doesn't know is that he will have to try to escape and deal with other kids in the library that try to cheat and go the easy way, that is the turning point in this book. The antagonist of this story in my opinion is all the other kids because most of them want to do Different things. The protagonist is Kyle. There are a few parts when Kyle figures out something important like ways to get out of the library and parts of the library like the windows that don't open and those were important things to figure out because he was trying solve the conflict. I liked this book because it had lots of details and it wasn't boring. I recommend and this book to anyone who likes adventurous books. I recommend this to 6 grade and up because it has some difficult words that some kids wouldn't be able to sound out. I hope you try this book out.
