Battlefield Mars Books in Order

A missing boy draws Captain Archard Rahn's security squad to a Martian farm, where a gruesome discovery reveals hostile indigenous life. Human colonists must defend New Meridian as an encounter with the planet's inhabitants escalates into a siege.

Survivors from New Meridian cross Mars's harsh terrain toward Wellsville while hostile Martians pursue them. Reaching the colony offers possible refuge, but persuading confident authorities to take the danger seriously becomes another struggle as the conflict widens.

Two human colonies on Mars have fallen to hostile indigenous creatures, leaving a third under threat. Earth sends forces and advanced weapons to save the remaining settlers, but the Martians' capabilities make the escalating struggle for survival uncertain.
