Someone is stalking Darla.
She has a lot on her plate already. Dealing with a breakup. Her best friend shutting Darla out of her life. A handicapped mother. Her career as a hospital nurse. She doesn't need slashed tires, threatening notes, or, least of all, a brick through her window.
She suspects her tormentor could either be her ex or her own father, who attacked and crippled her mother years ago. But she's just not sure, and there's no one but her dog to turn to.
Soon, she's forced to rely on own wits to protect her and her mother as the frightening threats become more and more frequent.
And are progressively more dangerous.
