Moh Kohn is a security mercenary, his smart gun and killer reflexes for hire. Janis Taine is a scientist working on memory-enhancing drugs, fleeing the US/UN's technology cops. Jordan Brown is a teenager in the Christian enclave of Beulah City, dealing in theologically-correct software for the world's fundamentalists-and wants out.In a balkanized twenty-first century, where the "peace process" is deadlier than war, the US/UN's spy satellites have everyone in their sights. But the Watchmaker has other plans, and the lives of Moh, Janis, and Jordan are part of the program. A specter is haunting the fight for space and freedom, the specter of the betrayed revolution that happened before. . . .With The Star Fraction, Ken MacLeod burst onto the SF scene and began the Fall Revolution sequence that continued with The Stone Canal, The Cassini Division, and The Sky Road.
