The Galaxy’s Worst Mercenaries picks up the comedic spirit of Dumb Luck and Dead Heroes with a new cast. The Kaelen Extraction (2025) and The Calypso Enigma (2026) follow a group of mercenaries who are, as the title suggests, terrible at what they do.

The series is still early with just two books out, but it already has the same mix of action and self-deprecating humor that made Ramirez’s longer series popular. Readers who enjoyed Dumb Luck and Dead Heroes will feel right at home here.
