Don't Make Me Smile — Barbara Park

DON'T MAKE ME MAD
Charlie Hickle decides he'd rather live in a tree when his parents tell him they're getting a divorce. How could they ruin his life this way? Don't they know he'll go nuts?

Well Charlie's got some plans of his own. He refuses to eat his mother's nightly macaroni dinners, sets up big-mouth MaryAnn to break the divorce news at school, and pulls a gagging act when his father takes him to the zoo.

With the help of an unexpected friend, Charlie realizes he's not going nuts after all. But not before he makes one last attempt to get his parents back together again. Fortified with a strong will and a sense of humor, Charlie just won't give up!
