Widow and single mother, Rebecca Noland, wants nothing more than to rekindle the passion with her overworked fiancé, Detective Dan Slaviche. Expecting to surprise him by slipping into his apartment before he comes home from work, her curiosity gets the best of her when she discovers the key to unlock his desktop. What she finds is a nightmare that sends her, along with her seven-year-old son, running for their lives. Terrified and broke, her only option is to flee to her family’s estate in Tremble, Tennessee, where memories of her mother’s violent death still haunt her childhood home. But bad memories aren’t the only things that await her. As Dan abandons all morals in his attempt to locate his bride-to-be, Rebecca struggles to make this house a home for her son while growing closer to her next-door neighbors. But her sanity comes into question when she realizes that her mother’s murderer is lying in wait within the home, and he’s intent on destroying anyone who tries to come between him and the object of his deadly obsession… her.
