The Traveler by Tom Abrahams Books in Order

Five years after the Scourge kills most of humanity, Marcus Battle lives alone on his fortified property with his grief and his guns. When a terrified woman runs to him for help, his sealed-off world cracks open.

Driven from home, Marcus Battle heads into a harsher world on a mission to find a missing child. The journey offers a shot at revenge, but every mile pulls him deeper into the chaos left by the Scourge.

Marcus has survived the plague and escaped the cartel, only to find a new frontier shaped by walls, resistance, and hard choices. The fight shifts from simple survival to deciding what kind of future is worth risking his life for.

Marcus is tired of running, but the shattered world refuses to leave him alone. As enemies close in, a new threat rises that could turn a bad apocalypse into something even worse.

After a brutal attack destroys his fragile second chance, Marcus Battle goes hunting for the men responsible. It is a revenge story with no safe stops and very few mercies.

Lou is young, quiet, and deadly, trained by her father to survive a ruined world. When she is left alone in post-Scourge Texas, she has to decide whether skill is enough to keep her alive.

Marcus Battle makes one last push to get his friends beyond the reach of an oppressive government. The road to the rumored refuge called the Harbor is long, deadly, and far from certain.

A decade after disappearing beyond the wall, Marcus Battle is pulled back into danger when an old friend needs help. The world is older, meaner, and still not finished with him.
