When Marshall King and Elyse Alton wake up tangled in each other's arms with zero memory of how they got there or even who they are, it's the start of a long journey through their separate pasts and shared future.

Terrified by their amnesia, they make a pact to find the answers that could restore their missing memories. As they piece together clues about their lives, they discover that they're in the idyllic resort town of Summer Falls, where darkness lurks beneath the town's perfect facade. Not only is the town haunted by sinister ghosts, but non of its living inhabitants retain bad memories of anything-not the death of Marshall's mom, not the hidden violence in Elyse's family. Lonely in this world of happy zombies, Marshall and Elyse fall into an intense relationship, but the secrets they're trying to uncover could be the death of their growing love - and of everyone, and everything, they love in Summer Falls.
