A YA Ghost Story

The house across the street is finally sold, and a couple moves in. While doing her homework, Morgan looks out and sees a guy about her age in the window on the third floor. As he’s staring right at her, she waves, but he doesn’t wave back. Mortified, she closes the drapes and berates herself for trying to be friendly.

Who's the boy? Why isn't he in school? Why do his parents deny having a son?
