Aliens Ate My Homework by Bruce Coville

This book has a fun little plot, and I gave it a rating of three out of five. Rod is intent on finishing his paper mache volcano and not getting beaten up by the school bully, Billy Becker. Then, a tiny spaceship crashes into his volcano, and Rod gets involved in the search for an intergalactic criminal, Billy Becker. It turns out Billy is actually an alien and is wanted for cruelty, the worst offense in the universe. Billy is not going to be captured easily, and a human like Rod might create problems for the intergalactic search team. He doesn't have any special powers or cool weapons, and he has a bad habit of always telling the truth.

The plot is simple and goofy, but it's fun. Rod's interactions with the aliens are humorous, and his truth-telling sometimes creates problems. As might be expected, trying to keep the aliens secret from your mother and best friend is difficult, but they probably won't believe you anyhow.
