Those looking for a new group of classic, hard science fiction writers need look no further than the latest volume of Galaxy's always-reliable original anthology series. A distinguished panel of judges, including Orson Scott Card, Larry Niven and Jack Williamson, selected 13 quality stories by relative newcomers touched with imagination and inventive plotting. The standout is Jeff Carlson's ""The Frozen Sky,"" a pulse-pounding account of an encounter with extraterrestrial life beneath the surface of Jupiter's moon Europa, but several others will linger in the reader's mind. Fresh names worth watching include Tony Pi, who presents a chilling story of the world's end, and Douglas Texter, whose vision of reality television's future features time-traveling lensmen sent to capture historic events. Also included are essays by Hubbard and artist Judith Miller, and illustrations from a number of different artists, a mixed collection marked by occasional brilliance. While readers will relish these short pieces, many of the ideas explored in them would likely work well in a longer format, auguring well for the future of these talented up-and-comers.
