Radcliffe Prep. The third most haunted school in the country, where a student disappearance isn’t uncommon and no one dares stay in the library after dark. And Este Logano enrolls with the hopes of finding her dead father.

Not literally, of course. She doesn’t believe in ghosts. Going to her dad’s school just seems like her best hope at figuring out who he was.

But then Este meets Mateo, who is maybe—probably—definitely—a real ghost. And an annoying one at that.

When Mateo frames Este for the theft of a rare book from the library’s secret spire and then vanishes, Este will have to track him down or risk being expelled and leaving Radcliffe early just like her father did.

Except following her father’s footsteps might be more dangerous than Este ever anticipated. As she investigates the library with its secret passageways, hidden tunnels, and haunted halls, she learns that the student disappearances aren’t just myth. And if she isn’t careful, she’ll be next.
