WINNING, REDEFINED.On the orbital Ring, solar sails ride the Sun's breath through a Corridor that answers to character as much as calculus. Captain Zuri and the Heliograph crew learn a new physics: pressure follows consented vectors, Shadefall stops wars before they start, and the fastest line is the one that keeps your neighbor.When an envoy invites them Further, the race spills earthward. Councils, welders, ward nurses, students, and kitchens come aboard, throwing Crowns and Spirals that open "Minor Doors" for real lives. The Braid becomes a culture-teachable, fixable, contagious.From flare-mouth sprints to a ground-led passage conducted entirely from below, Sunship Regatta is a shimmering, human-scale space epic about making rooms kinder at speed. If you loved the heart of Becky Chambers, the civic care of Ursula K. Le Guin, and the bright math of hard SF, this is your next passage.
