On the mirror, in red-brown lipstick smears is a message that was absolutely not here when I walked in. “Stay hidden.”

It’s not like Mallory wanted to leave home, but it wasn’t safe to stay. So she sleeps at her best friend’s house and spends most of her time at the library figuring out what comes next, determined to not live in fear like her mother.

Spencer volunteers at the library. Sure, it’s community service for a stunt he pulled, but he likes the work. And it’s the perfect escape from his parents’ pressure to excel at school, at ice hockey, at everything. Especially after he meets Mallory.

Then a tragic death turns their sanctuary into someplace sinister. Ghostly footprints strange scratching sounds, scralled messages on bulletin boards and walls… Mallory and Spencer don’t know who or what is responsible, but one thing is for sure: they are not as alone–or as safe–as they thought.
