Worn down by the misery she witnesses in her job and escaping a bad relationship, Catherine moves across the country to Kingston, New York to settle into a quiet hiatus. When she meets sensual and mysterious Tom, she delights in a new romance.

But Tom has secret upon secret, and as Catherine soon learns, some of them are deadly. He is Thomas Ambrose, exiled billionaire scion of a monstrously corrupt family, and his wealth and past aren't all that he is hiding.

She is also in danger...the evil society, the target of the Black Mask's vigilante justice, is trying to kill her and stop her investigation. Which of the two men she desires will she choose to protect her? Or does she have a choice?
