Everly Black can’t tell anyone she’s a reaper. If she does, the Institute kids will die to become one. To protect her secret and keep them safe, Everly’s mother forces her to babysit.

Six years ago, Everly’s father went missing when poltergeists took him. As soon as she graduates, she’s going to find him. No one will stop her, not even Levi Silver, the hottest reaper she knows. He’ll either help her or get in her way.

Close to graduation, poltergeists trapped in the Grim Reaper's realms flee. Everly goes after them and sends them to the afterlife. But no one knows why it happened. If she stays to figure out why, she won’t find her father. If she leaves, humans and reapers will continue to die.
