When seventh grader Nicholas V. Landrew, his beloved pet gerbil Henrietta, and a package of ground beef are beamed aboard an alien space ship, they soon find themselves on the run in a madcap chase across the universe.
All Nicholas wants to do is get back home before his parents find out and ground him forever, but with the Universal Police hot on his trail, that won’t be easy. Before it’s all over, Henrietta will find herself safely ensconced back in her cage, Nicholas will be crowned Emperor of the Universe, and something even more surprising will happen to the package of ground beef.
