Magic Tree House
Junie B. Jones
Deciphering a code they find in a library book, best friends for life Amos and Dunc stumble onto a burglary ring. The burglars' next target is the home of Melissa, the girl of Amos's dreams (who doesn't even know that he's alive). Amos longs to be a hero to Melissa, so nothing will stop him from solving this case--not even a mind-boggling collision with a jock, a chimpanzzee, and a toilet.
