Adam Wesley and his friends have escaped the city, leaving behind the Nest after a deadly attack—the one place they thought was safe. As the reluctant leader, Adam struggles to hold the group together as relationships grow tenuous under the relentless stress of survival.

The Transition, a wholesale restart of society, is well underway, and the bot menace is everywhere. Travis Eckart, the mastermind behind the bots, is now almost entirely dependent on NXES—a powerful AI he developed to help win the war. However, NXES has its own agenda, and Travis must confront his own blind ambition if he is to discover the truth before it’s too late.

Adam and his friends embark on a perilous journey to Cheyenne Mountain, the secret stronghold of the burgeoning rebellion against the Transition. They carry with them information that could change the course of the war, but only if they can reach the mountain in time.

Along the way, they will discover they aren't the only ones fighting for survival. There are others just as desperate as they are, and it's not always clear who they can trust.

In a world where loyalty is rare, and peril is ever-present, Adam and his friends must rely on each other to navigate their harrowing journey.

Dive into this gripping tale of courage, friendship, and the fight for survival in a world on the brink of a devastating rebirth.
