Prom was supposed to be the biggest night of senior year, but for Jenny Lewis it was the night she almost died. The night someone drugged her, loaded her in a car, and dumped her body in the river.

The next morning, her soaked prom dress was found on the riverbank. Her body was never found. People whispered that she'd killed herself or gotten drunk and stupid. People moved on, went to college, and stopped thinking about her. Months later, her ex-girlfriend and three other classmates received a text from an unknown number accusing them of her murder and claiming to have proof.

The text? It came from Jenny, not dead and ready to figure out who tried to kill her. There's going to be an impromptu reunion and no one is leaving until the would-be murderer steps forward.
