How do you catch a fugitive who has nothing to lose?

US Marshals Madison James and Jonas Quinn have orders to transport two high-profile prisoners across the country on a private plane. But when the plane experiences engine trouble en route from

the Pacific Northwest to Colorado, the pilots crash-land the aircraft deep in the heart of the sprawling Salmon-Challis National Forest.

With both pilots and one prisoner dead—and one fugitive on the run—Madison and Jonas must negotiate the rugged and remote backcountry as they track a murderer who is desperate to disappear … and will do anything to stop them.
