When he thwarts an attack on the Appalachian Trail Peter Ash finds himself battling a team of professional killers in this propulsive new thriller from the bestselling and award-winning series.

For the troubled soul of Peter Ash there's no balm like time spent in the outdoors. So a through hike on the Appalachian Trail should be a relaxing break.

But an encounter with a suspicious old man is only the first sign that something isn't right. Even though he's been warned to mind his own business by the other man, Peter isn't about to stand by and watch a senior citizen be menaced by two gun-wielding thugs.

Saving the victim doesn't end the threat. In fact, Peter soon finds himself being chased by a team of professional assassins as well as law enforcement. Intervention quickly morphs into "in over his head," but that's nothing new for Peter Ash.
