The first story in which Sean Williams used the 'd-mat' technology that would become central to the Twinmaker universe:
The world of “New Flames” doesn’t quite map onto either Twinmaker’s or The Resurrected Man’s. Marcus deBarrow is never referred to again, and “D-mat” quickly becomes “d-mat”. If you’ve read Crashland and you read this story you’ll see that I changed a lot of the details–including the phrase “loose gluons”, although I’m not sure if “unstable matter” makes any more sense.
