Evie works the night shift at a call center. Not just any call center - the one where the dead call in with unfinished business. Most of them want to say goodbye. Some want revenge. And a few just want to know what happened to their cat. But one night, a girl calls who doesn't know she's dead. Her name is Iris. And she keeps calling back. Each time, she remembers more. Each time, the world around Evie slips a little further out of sync. Because Iris isn't just a case. She's a key. And if Evie answers her final call... she might not come back.
