Two distinct tales of survival and confrontation force ordinary men into extraordinary circumstances where their pasts and physical endurance are tested to the limit. In High Citadel, pilot Tim O'Hara must lead a group of survivors against armed militants in the frozen Andes, relying on ingenuity to overcome superior firepower. In Landslide, geologist Bob Boyd uncovers a buried history that threatens his identity and pits him against a powerful corporate dynasty in the rugged terrain of British Columbia. Both narratives utilize a third-person perspective to track the protagonists' desperate attempts to navigate hostile environments and lethal human adversaries. The stories emphasize the clash between individual resilience and overwhelming external threats.
