BOOKLIST: "Such variety assures continual interest...the authors...certainly know their craft." Long after our species and all its works have turned to dust, the Moon-landing sites will still show evidence of our time here on Earth. Imagine future explorers from among the stars interpreting that. The astronauts' footprints should last longer than the fossils in the Olduvai Gorge. Here are twenty-one views of that. Stories by Brenda Cooper, James Van Pelt, Lawrence M. Schoen, Heather McDougal, and more. Edited by Jay Lake and Eric T. Reynolds. Presented by Hadley Rille Books.
