Passage at Arms

Series background & context
Starfishers is Cook’s signature space-opera setting, a universe of merchant Houses, secretive aliens, and private armies that behave like feudal corporations. At its core is the Storm family, a mercenary dynasty whose fortunes are bound up with the Sangaree, an alien race that once enslaved human worlds.
Centuries before the main story, a Storm-led strike freed human slaves from the Sangaree on a hellish world called Prefactlas. Only one Sangaree heir survived and swore a long, patient revenge. When the trilogy opens, that vendetta is finally ripening. In Shadowline, much of the action plays out on Blackworld, a tidally locked planet where every scrap of habitable land lies along a narrow band between burning day and frozen night. Rival forces fight over industrial riches while old scores come due.
Later volumes follow Mouse Storm and Confederation agent Moyshe benRabi as they chase Sangaree harvestships called Starfishers, which tend living energy beings in deep space. Those Starfish produce a substance that makes faster-than-light travel possible, and whoever controls that supply controls interstellar civilization. Battles range from close-quarters boarding actions to complex fleet engagements around fortified mysteries like Stars’ End.
Along the way Cook folds in questions about slavery, corporate warfare, and the ethics of building an economy on the backs of literally inhuman labor. The Storms are efficient killers but not simple heroes, and the Sangaree are enemies with their own logic rather than faceless monsters.
Readers who like the scale and hardware of classic space opera but prefer Cook’s terse, ground-level storytelling will find a lot to enjoy here. This background helps sketch the long feud between Storms and Sangaree, explain what the Starfish actually are, and show how the three books link together into a single, escalating conflict.
