 All of William Slater's Juvenile fiction books are worth reading. This one is especially entertaining and crazy. This kid starts playing a board game with his crazy new neighbors, where each player represents a different planet and a different alien race, and the goal is to be the last player standing and holding a card called the pig. Well, it turns out it's not a game, and somehow this kid has ended up being appointed the representative of Earth. It's really clever, and nothing is ever what it appears to be, and like all of William Slater's books, I recommend it.
