Days away from testifying in a bank robbery and murder case, witness Kari Danville's safe house is breached, forcing her to run for her life. Scared, alone and pregnant, her only hope for survival rests in the protection of FBI agent Marc Callahan. With everyone in uniform a suspect, Marc goes rogue to keep her alive. Deep in hiding as the holidays approach, the vulnerable mother-to-be proves a dangerous distraction. But Marc can't lose another witness on his watch. As the Christmastime trial draws near, the killer stalks ever closer. And Marc must find a way to shield Kari--and her unborn baby--long enough for justice to be served.
