But Nathaniel has been obsessed with her since the day she married his brother—and he's been waiting for her to make the first move. As they circle each other like predators, secrets unravel: the surveillance he's kept on her for years, the pregnancy that could belong to either brother, the betrayals that run deeper than murder. In this deadly game of revenge and obsession, the only question is: who will destroy whom first? Or will they destroy each other?
