A year ago in Afghanistan, Green Beret Heath Daniel’s career was destroyed. Along with his faith. Now he and his military war dog, Trinity train other dogs and their handlers through the A Breed Apart organization. The job works. But his passion is to be back in the field. The medical discharge says it can’t happen due to the traumatic brain injury that forced Heath to the sidelines.

Until. . .

Military intelligence officer Darci Kintz is captured and the geological survey team she’s covertly embedded with is slaughtered while secretly tracking the Taliban. It’s clear only one dog can handle the extreme conditions to save her. Trinity. Only one man can handle Trinity. And time is running out on the greatest—and most dangerous—mission of their lives.
