Knife to a Gunfight (2013)

Joely McCullough is terrified. She thought her best friend Abbey would always be there for her, understanding and accepting and laughing to the end. She thought her lover Wes would save her from the perfect-looking marriage, with his solid arms and sure gaze. She thought they were in love. And an hour outside the city, a dark figure stalks the storage unit hallways and metal boxes, luring victims to a silent, bloody end. Joely thought her connection to this killer would stay a secret forever. Joely was wrong.
