Some people die. Some disappear. And some... are erased. For the past three years, Amelia has been doing everything she can to survive - burying her grief, outrunning her past, and hiding a truth she barely understands. She may look human, but she isn't. Not entirely. When her best friend vanishes without a trace, leaving no memory of her behind, Amelia comes face to face with the terrifying truth: something dark is hunting her. And this time, surviving won't be enough. The shadows are closing in. People she loves are disappearing. And no one is safe - not even Ezra, the boy she loved enough to let in. But when the monsters come, Amelia will have to decide how far she's willing to go to protect what little she has left. Because the creatures that took Kayla are coming for her next. And they don't just want to erase her. They want to claim her.
