Books and Stories

Darkness Evolved follows Jose Garcia and the Variant Hunters after heavy losses have hardened Garcia's hatred of the Variants and the people who created them.

Emergence

Emergence begins the New York firefighter-and-civilian branch with Meg Pratt at home with her husband, Tim, trying to process reports that sound impossible.

Extinction Age pushes the series into full military collapse and desperation.

Extinction Ashes

Extinction Ashes pushes the Dark Age conflict into larger command and territorial stakes.

Extinction: Thailand

"Extinction: Thailand" is an investigative side story by Russell Blake collected in Missions from the Extinction Cycle, Volume 1.

Lost Valley

Lost Valley begins the Survival branch at its most intimate scale: one retired operator, one working dog, one woman and her son, and a Boy Scout camp that might become.

Missions from the Extinction Cycle Volume 2

Missions from the Extinction Cycle Volume 2 continues the anthology function with stories that read like dispatches from the edges of the main war - new outposts, new survivors.

Outpost 46: Deadwood

Outpost 46: Deadwood is a military outpost story centered on Lieutenant Jim Flathman and the desperate defense of a fortified position during the outbreak.

Penance

Penance continues the Redemption branch after the first collapse. Meg, Jed Welch, and the New York survivors are no longer only reacting to the impossible - they are living.

Resurgence

Resurgence completes the trilogy by moving its survivors toward renewed purpose.

Satan's Gate

Satan's Gate widens the Survival branch beyond whether Lost Valley can survive, forcing the community to reckon with a broader military breakdown and the human threats that come.

The Five Pillars

The Five Pillars is the New Zealand branch's major resistance-and-reclamation step.

The Fourth Phase

The Fourth Phase moves the New Zealand branch from immediate family survival into the harder work of organizing people.

The Redemption Trilogy

The Redemption Trilogy collects Emergence, Penance, and Resurgence - the New York firefighter-and-civilian branch of the Extinction Cycle, centered on Meg Pratt and Jed Welch.

The Rule of Three

The Rule of Three begins the New Zealand branch by placing family survival at the center of a global catastrophe.

The Sixth Law

The Sixth Law is the branch's post-reclamation warning, jumping roughly ten years beyond the initial apocalypse.

Warrior's Fate

Warrior's Fate brings the Survival branch to its mature form. Lost Valley is now a community with families, youth defenders, and outside allies - including Palomar-area.
