She's beautiful. She's charming. She's going to destroy your life.

When her only son leaves for college, Helen Martin thinks her biggest worry is an empty house.

Then Dakota moves in next door. Young, beautiful, and brash, Dakota quickly attracts the ire of the homeowners association — and the wandering eyes of Helen’s husband, Sam.

But Helen is determined to be a good neighbor. When Dakota's violent ex-husband comes looking for her, Helen thinks she can help drive him away.

She's wrong.

What starts as a simple act of kindness spirals into a nightmare of obsession, lies, and deadly secrets that will threaten her marriage — and her life.

How far will Helen go to save herself, her home, and her family?
