The next installment in the pulse-pounding Gannon series, featuring murder, intrigue and a deadly new mystery that may just be his last.

Fresh from a lethal entanglement with some of the darkest players in the global intelligence services, Michael Gannon heads to the safest place he can think of: deep in the wilds of Utah on the ranch of one of his oldest and closest war buddies.

But when his friend’s brother is found dead in the rocky foothills of Grand Teton, Gannon realizes there are some things more important than keeping your head down.

Is his death just one in a string of grisly murders mysteriously occurring around national parks --- or a part of something even more sinister?
