Zero to hero

the long version

Billy Broccoli is a boy with questions: about his new school, his new step-family ... his whole new life, in fact. Hoover Porterhouse (aka the Hoove) is a ghost with all the answers. When a trick of fate makes them roommates, Billy discovers that having a ghost around might not be so bad after all. The Hoove is funny and cool, a great baseball player, and is a real people person (even if Billy is the only one who can see him). And with obnoxious school bullies out to demolish him, Billy can use all of the advice he can get. With Hoover by his side, Billy just might get in style, get even, and conquer the school.
