Gwen Maner is a widowed single mom, returning to her Ohio hometown with her daughter. And thanks to former acquaintance Nicola Kimmel, this is the start of Gwen's new and promising life.

Nicola's secured Gwen a lucrative job, rented Gwen a house on her same street, and won the heart of Gwen's daughter, but she almost seems too good to be true. She's so selfless. So charismatic. And so take-charge. Gwen is sure Nicola is yearning only for someone to get close to. After all, according to Nicola, her marriage is falling apart, and her best friend just up and left one day.

But how well does Gwen really know Nicola? What does Nicola ultimately want? As their lives become more entwined, and Nicola's grip tightens, Gwen begins to think that Nicola isn't helping Gwen and her daughter but vying for control of every aspect of her life. And the consequences may be deadly.
