Caleb O'Halleran is a Tactical K9 Specialist with the FBI's elite Hostage Rescue Team. Finding the traitor responsible for his K9 partner's death is the only thing that matters ... until he meets an enchanting, strong-willed doctor.

A noble doctor determined to help others ...

Dr. Dawn Pannikos is a busy ER doctor with a surly teenage sister to raise and a past that has taught her not to trust love. There's no room in her well-ordered life for an irresistibly charming ladies' man with shadows around his heart.

Two innocent women dragged into a nightmare ...

Dawn and her sister become prisoners of a psychopathic cult leader and are plunged into the middle of a dangerous FBI operation. Will Caleb and his new K9 partner, Jake, find them in time, or will he be too late to save the woman who owns his heart?
