In a secluded cabin nestled deep within the woods, Gus spent his childhood with his father, absorbing hard-won lessons of resilience and the perils that shadowed the world beyond their boundary.

Gus accompanies the stoic Big Man into uncharted territory. Dr. Singh uncovers the price of Rani’s salvation. Aimee discovers a fresh start amidst the ruins of civilization.

Determined to see Gus safely departed, Big Man devises a plan for concealing him within the ordinary. The Singhs arrive at a neighborhood gathering, only to find the festivities taking a decidedly unsettling turn.

As the shadow of his past closes in, Gus finds refuge with unexpected allies. Meanwhile, Dr. Singh worries that an inquisitive neighbor might expose Rani’s hidden truth.

Gus and Big Man take on a fellow traveler who proposes a dangerous shortcut, and Aimee’s haven is suddenly at risk. The Singhs are running out of time.

Driven by desperation, Dr. Singh offered a daring promise. The disappearance of a cherished keepsake set the stage for a perilous journey to Colorado. Meanwhile, The Last Men drew nearer to the Preserve.

The pursuit of Birdie, and the unraveling of her ties to his father, throws Gus into a disorienting state, forcing him to re-evaluate the very foundations of his understanding.

The world tilting on its axis, Gus fled, acting on impulse. Meanwhile, Big Man wrestled with regrets from years past. And Aimee prepared for a final confrontation with General Abbot.
