The clock was ticking....

Detective Rafe Morgan knew that, as a psychologist, Darby Steele was used to people coming to her in need. But now she was the one in danger. A serial killer had made her a pawn in a sick game, sending her photos of his targets with clocks counting down. As a part-time bomb technician, Rafe was uniquely capable of keeping Darby safe. Usually psychologists rubbed Rafe the wrong way, but when it came to Darby, his urge to protect and serve went way beyond the badge. Getting to know the beautiful doctor had opened Rafe's eyes - and his heart. But if their elusive bomber had his way, Rafe would never get a chance to prove just how far he'd go to keep Darby alive.
