Four Worlds is where Ramirez’s career began. The Five Warriors (2019) introduced his universe, and the series continued with The Truth (2022), Subversion (2023), Revolution (2024), and Wrath of Mars (2024). The books follow an interplanetary conflict that escalates across the five volumes.
The series has a more straightforward military SF tone compared to the comedy of Dumb Luck and Dead Heroes. It shows Ramirez working out the ideas and settings that would later fuel his larger body of work. Readers interested in the foundations of his fictional universe should start here.
