Why I'm Not Afraid of Ghosts (Ghosts of Fear Street #23) R.L. Stine - Vintage Paperback

BOO WHO?

Oliver Brown doesn’t believe in ghosts. Even though he lives in a house on Fear Street that’s chock full of them! Robbie should know—he’s one of the ghosts. And his new neighbor doesn’t scare easy—even though he’s tried everything he can think of to send Oliver screaming.

Robbie’s got one trick left up his sleeve. And it has to work. If it doesn’t, he’ll have to give up the ghost business forever.
