Seeing Things by Sonora Taylor

Abby Gillman has discovered that with growing up, there comes a lot of blood. But nothing prepares her for the trail of blood she sees in the hallway after class - or the ghost she finds crammed inside an abandoned locker.

No one believes Abby, of course. She’s only seeing things. As much as Abby wants to be believed, what she wants more is to know why she can suddenly see the dead. Unfortunately, they won’t tell her. In fact, none of them will speak to her. At all.

Abby leaves for her annual summer visit to her uncle’s house with tons of questions. The visit will give her answers the ghosts won’t - but she may not like what she finds out.
