Locked out of her own shelter by her boyfriend during a deadly blizzard, eighteen-year-old Wren dies in the snow - then wakes up thirty days earlier. This time, she stocks a secret refuge and keeps control of the supplies he plans to steal. As his ex spreads lies and her classmates turn against her, Wren fights back with hidden cameras, sealed lockers, and a quiet classmate who offers her his coat. But saving herself means more than revenge. She must stop giving away her own place in the warmth.
