Ralph McDuff: Certified Giant (Major League Chillers Book 17)

Ralph McDuff is tired of being short. He's tired of his sister bossing him around, of the kids at school who tease him in gym class, and he's tired of feeling insignificant. If only he were tall, everything would be different. But it doesn't work like that. You are what you are, right? Wrong. Everything changes when you're abducted by aliens. And anything is possible. They say they want to help Ralph. They say he's been selected to receive biological modifications. They say a lot of things, those aliens. But can they be trusted?
