Former FBI agent Brooke Fairfax is on the verge of starting a new, simpler life with Irish mogul Declan O'Roark. But when tragedy strikes the night of Brooke's and Declan's engagement party, Brooke has no choice but to track down Romeo, the serial killer stalking her for years. And Declan vows to help her put an end to the man who desires Brooke so completely, he's willing to kill to possess her.

When a woman from Declan's past emerges, promising nothing but grief for the already struggling couple, Declan is faced with a dilemma: take the time to get the troubled woman from his past the help she desperately needs or join the woman he loves in the struggle to stop Romeo before he makes Brooke his next victim. The problem? Declan's love for Brooke might not be enough to stop Romeo from killing them all.
