Brand-new third grader, Chris Anderson, has his whole year mapped out, and it starts with two words: BE NICE! Easy enough, right? Well... ...it seems like it at first. But when Chris and his best friend, Bobby, meet new kid, Kevin, being nice proves harder than Chris thought. Kevin is EVERYTHING Chris trying not to be. He's rude, he's mean... and Bobby seems to like him much better than the new Chris. Try as he might, Chris cannot get on Kevin's good side, who is now acting like a bully, and has Bobby acting like it too! Once Kevin and Bobby create a top-secret treehouse club in Kevin's backyard and leave Chris out, Chris is left with no other choice. THIS MEANS WAR!
