Enhanced descriptions from Syndetics:

What is the difference between justice and revenge? In this buzzworthy new standalone thriller by New York Times bestselling author Lisa Unger, two wronged women on very different paths find themselves in the same dark place...

Claudia Bishop's perfect life fell apart when the aftermath of a brutal assault left her with a crumbling marriage, a newborn daughter, and a constant sense of anxiety about the world around her. Now, looking for a fresh start with a home restoration project and growing blog, Claudia takes on a crumbling old house--one that unbeknownst to her has an ugly history and may hide long buried secrets.

For Zoey Drake the defining moment of her childhood was the horrific home invasion murder of her parents. Years later, she has embraced the rage that fuels her. Training in the martial arts has made her strong and ready to face the demons from the past--and within.

Strangers to each other, and walking very different paths in the wake of trauma, these two women are on a collision course--because Zoey's past nightmare and Claudia's dreams for her future take place in the very same house. As Zoey seeks justice, and Claudia seeks peace, both will confront the monsters at the door that are the most frightening of all.
