In the first book of the Alien Next Door series, an alien boy named Zeke tries to fit in and adjust to life on Earth, while a classmate, Harris, suspects that Zeke might not be quite what he claims to be.

Zeke the alien is on his way to his first day of school, feeling down because he has to start over again on a new planet, as his scientist parents constantly move to wherever their research takes them. When he gets to school, no one seems to notice anything strange or different about him except Harris, a kid obsessed with science fiction and aliens. Harris sees Zeke doing extraordinary things but can't convince anyone, least of all his best friend, Roxy, that Zeke might be an alien. Roxy just thinks Harris is jealous that she's becoming friends with Zeke. But when Roxy invites Zeke over to Harris's house, will Harris find a way to prove that he's right?
