The Millennium Express: The Collected Stories of Robert Silverberg, Volume Nine — Robert Silverberg

But, for all that, I went on writing short fiction all through the seventh and eighth decades of my life, and though I'm not very active these days, I would still pay attention if someone were to approach me with an interesting and challenging short-story project, or if some absolutely irresistible story idea were to come into my mind. I will not, at this point, try to claim that the stories that are collected here are the last short stories I will ever write. Surely some editor, in the years ahead, will tickle my imagination with a proposal I can't resist. But I doubt that will be happening very often; and, meanwhile, here's the harvest of the fourteen years that began in 1995--not an enormous number of stories, no, but stories nevertheless that I think are worth reading and reprinting.
