The Planetsider Trilogy Books in Order

Ranger Ethan protects a settlement on a devastated planet until a crashed spacecraft brings strangers from the moon. Seeking answers about his world’s destruction, he joins their mission and becomes caught between surviving factions still fighting a century-old war.

Ranger Ethan searches the wastelands beyond humanity’s fortified settlements for supplies and answers about the apocalypse. While sickness transforms survivors into dangerous roamers, a war among remnants of the old civilization threatens to return from space.

With refugees safe on the planet, Maria Salus returns to the moon to confront General Kurren’s coup. Ethan and Summer prepare to fight the mutated Maddened, but overwhelming opposition forces them toward a dangerous alternative that depends on finding one man.

Captain Maria Salus’s defiance once opened a path toward reconciliation between rival human factions. Five years later, she flees planetside with refugees, seeking help from Ethan and Summer while dangerous radiation and General Kurren’s soldiers threaten their escape.
