Fifteen-year-old Paul has been obsessed by the idea of an alien invasion for as long as his family and friends can remember. Throughout his life, Paul has claimed a number of alien sightings. Despite all the false alarms, however, Paul is still a true believer in the extraterrestrial-and his instincts kick into high gear when Mrs. Ramblows moves in next door. On the outside, Mrs. Ramblows appears to be a sweet little old lady who enjoys gardening and afternoon tea. The truth is the gray-haired neighbor is an alien from the planet Starrbile and her mission on Earth is to capture an earthling child and return with him (or her) to Starrbile. Paul's got to stop the alien before it's too late-but the trouble is, nobody believes him! How can Paul convince all he's telling the truth?
