In this newest Awol hiking thriller, Karl Bergman, whose trail name is Awol, begins to thru-hike the 3,100-mile-long Continental Divide Trail at the Mexican border. By the time Awol and his dog, Blazer, reach the Colorado Rockies, he has uncovered information about a terrorist plot. Awol asks his son, a graduate student at UCLA, to give details to old friend, Detective Vincent Sacco. Awol tells his son he doesn't want to get involved and continues his thru-hike. Awol is beyond annoyed when FBI agent, Diana Santos, finds him on the CDT and asks him to work with her and infiltrate.
