      I read this book and it is AWSOME!!!!! Here is what it is about:so a guy named Mr.Lemenchello started this great library because it had all kinds of books and there were just a lot of awesome stuff. Some kids have to escape the library and it proves a lot harder than it seems. They can not go through the front door or fire exits. If you read this book make sure to check out the second book!!! The second book is called Mr.Lemenchello's library Olympics. Love,love,love them!!!

            This is the first book in the Lemoncello series, and it was so great I reread this book multiple times. This book is about Mr.Lemoncelo, a rich billionaire who made a hight tech library that 12 kids have to escape from. Kyle, the main character, facing many challenges in order to escape the library, such as Charles, the bully, and the enemy. Can Kyle win the grand prize and escape the library? I loved this book. I hope you guys love this book as much as I did!

              This book is about a boy called Kyle, and he is a big gamer. His favorite games are made by his hero, Luigi Lemoncello. He created a library in the town where he grew up. And selected twelve twelve-year old kids to participate in a library lock in. The way you are chosen is by writing the best extra credit essay Kyle and eleven other kids are able to compete for the biggest prize they have ever wanted, they will be...(Sorry, but I can not spoil the ending, so read the book to find out) a great book with puzzles and at the back is a list of all the books mentioned in the story, so a good reference when wanting to read good and popular books. (There is also a secret puzzle for YOU to do.) This book I would recommend to people in third to sixth grade that love puzzles.

                This book is about 12 people who get chosen (by writing essays) to be the first library card holders of the new library. The library was created by the famous game inventor, Mr. Lemoncello. What they don't know is that they will be part of a game to escape from the library. I thought that this was a very fun book. It has lots of puzzles and riddles in it. I recommend this book to anyone who loves puzzles and adventures!

                  Kaiser Weist #27 February 4, 2020 This book’s genre is Mystery and Adventure and it was written and found by Chris Grabenstein. The first thing that happens in the story is, Kyle and his brothers are playing a game. Kyle and one of his brothers found what they needed and were sprinting to their house to get the last thing they needed before one of them got it. Meanwhile, Kyle’s other brother was stuck trying to get a dog toy. Kyle runs through the garden while his other brother ran through the house.Kyle made it to the basement window and kicked it open and got the last thing he needed first. The main characters are Kyle Keely, Akimi Hughes, and Sierra Russell.Kyle is the MAIN main character and he’s super smart and he likes to play games,video or board, no matter how old. Akimi is Kyle’s best friend and loves games too, and she is super smart like I said for Kyle.Sierra might be the smartest one of them all, she always has her nose in a book and she only takes her nose out of a book to help people. One of the key events that happened in the story that added to the plot was a bully that got invited to the lock in made his team mate steal one of the other team mates library card to go into their meeting room to copy down clues that they found to see if they were on the same track as them because they thought that would be a problem.The other key event that added to the plot was that the bully tried to steal one of the books that the other team was pulling out of the bookcase.Then he grabbed it and slammed into the person that was holding the book. The main character changes from the beginning of the story to the end because at first he is all about video and board and then on pgs.201-202 it says,” But finally, after the inside of his mouth had turned to sandpaper he said No thanks Charles.We’re just gonna,you know, read.” So that says to me that he is getting over video games and he wants to read more. One unanswered question that I’d like to ask the author is how did you come up with Alexandriaville,Ohio for the location and which dog is fred in Chitty Chitty Bang Bang? The thing that I enjoyed the most about the book is all the puzzles and clues and how hard it was for them to get out of the library and how long it took for them to solve the mystery. I would recommend this book because it is a good story and the author makes it seem like the setting is real but it is not real
