Katlin Musco is a guilty soul whose life has only ever had one constant: everyone else. Their problems are hers, and they make sure of it. Her parents' misery. Her sister's anger. Her brother's illness. It's all her fault, and it's all on her, despite having her own scars to bear. Every day is a coin flip to see which thing will destroy Kate next. But one rainy night, the coin flipped, and that constant broke.
During a record storm in the small town of Shapley, Katlin gets trapped in her apartment building with no power, no contact, and seemingly no way out. For what should be a night of reprieve from an endless stream of problems morphs into a nightmare, as a more personal issue progresses: the night wants her dead. Katlin must find a way out before it devours her.
