Set aboard a vast, aging generation ship called the Whorl, the novel follows Patera Silk, a resourceful and morally ambiguous priest whose rise from humble origins plunges him into political intrigue, religious rivalry, and social unrest. As Silk confronts corruption, assassination plots, and competing cults centered on enigmatic “gods” whose true nature suggests ancient technologies, he encounters shifting loyalties and personal temptations while the story probes questions of faith, power, identity, and the hidden realities of the world his people inhabit.
