Knights of the lunch room table the dragon player

This book is about three boy trying to win a game but someone is getting in his way. They have to win the game because the price is 300 hundred dollars and they need that money. The rest is the way the book is if stuff they go through to win or not win the game. The message in this book is the choices you make but I do not know for sure until I finish the book. If you want know more you have to read the book. :)
