A broken promise leads to a broken heart...and to danger.

When FBI Special Agent Alex MacGregor's sister disappears from her veterinary practice, it brings back the nightmare of his identical twin's kidnapping and death sixteen years earlier. Burdened by a large measure of guilt and responsibility for his brother's death, he has no choice but to take leave from the Chicago office's Violent Crimes Task Force and head to upstate New York, vowing he will find his sister. That's one promise he'll keep. Even if it means confronting Bette Smithson again, the sexy young woman he rescued from a stalker six months earlier and left behind.

Bette didn't want to call Alex. A gal has her pride after all. But his sister, Bette's boss, has gone missing which leaves her little choice but to call the handsome FBI agent who has ignored for her six months since he saw her off at the Nashville airport with a knee-buckling kiss and a promise to call. So much for promises.

Faced with a slow-to-react local police force, Alex and Bette work together to find his sister before the unimaginable happens. As both feared, their mutual attraction ignites into a full-blown passion. But when Bette's secret is revealed, will all chances for happily ever after vanish in the blink of an eye?
