These are all stories from the mid-1990s. I'd read most of them before, as most were originally published in Asimov's, including the novella version of Beggars in Spain. I never re-read books, but I read/re-read everything here. Nothing seems dated (except the years, as when the semi-near future is, say, 2016) and it's all first rate. Nancy Kress was at her peak when she wrote this, and she still is now.
