From the USA Today bestselling author of Diavola comes a darkly funny, blood-soaked horror novel about the terrifying seduction of unlimited power.

After years of caring for her dying mother, Martha Shaw feels empty, exhausted, and far older than her twenty-six years. So when her brother invites her to a weekend getaway at the opulent, two-hundred-acre country estate where his friend works, Martha reluctantly agrees. After all, what's the harm? The owners and all their staff will be gone. Security cameras will be off. The house will be theirs. For the first time in years, Martha might actually have fun.  

And it is fun, taking advantage of the historic mega-mansion and its vast grounds. Martha begins to feel human again. But when night falls, the rightful master of Newbourne Park returns—and she’s not alone. Suddenly, being caught trespassing is the least of their worries, because what steps out into the moonlight is something vicious. And hungry. 

What began as a lark becomes a bloody battle for survival, where greed and morality collide—and a woman must choose to bow, break, or bite back.
