When Marshall King and Elyse Alton suddenly 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, Marshall and Elyse make a pact to work together 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 mountain resort town of Summer Falls. Everyone seems happy there, but as Marshall and Elyse quickly learn, darkness lurks beneath the town's perfect facade. Not only is the town haunted by sinister ghosts, but none of its living inhabitants retain bad memories of anything--not the death of Marshall's mom, not the hidden violence in Elyse's family, not even the day-to-day anguish of being a high schooler.

Lonely in this world of happy zombies, Marshall and Elyse fall into an intense relationship founded on their mutual quest for truth. But the secrets they're trying to uncover could be the death of this budding love affair--and of everyone, and everything, they love in Summer Falls.
