An ex-Green Beret. His war dog. On the greatest mission of their lives. And probably their last.

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, have a chance to redeem their skills 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 killed while secretly tracking the Taliban in the beautiful but brutal Hindu Kush. It’s clear only one dog can handle the extreme conditions to save her. And only one man can handle Trinity.

Time is running out on the greatest—and most dangerous—mission of their lives.
