An ex-cop who cannot die. A moon full of settlers who cannot thrive. Mahina's terraformers built a high-tech urban paradise. Then Earth flooded the colony with desperate refugees, cop Sass Collier among them. The settlers who arrived with Sass died decades ago. Outside the citadel, their descendants die weak and young. Sass fought a rebellion against the city once. She won concessions to give the settlers a chance at health. She paid with 20 years in prison. Now she's out, a reformed character. She recruits a motley crew and finds odd jobs. She intends to mind her own business – how to make a profit with the skyship Thrive. But her fellow settlers are still failing. While her business model careens toward circus acts, Sass dares to defy the city again, to solve Mahina's failure to thrive. Pick up Skyship Thrive because you love upbeat character-driven SF with fun technology, and hard science fiction with rivets. Suggested for fans of Firefly, Jenny Schwartz's Xeno-Archaeologist, or Nathan Lowell's Golden Age of the Solar Clipper.
