Rewind — David D. Levine

Clark Thatcher is one of the elite: a surgically-enhanced soldier carrying in his very bones the Army's secret weapon. But when he decides that enough is enough, he must decide if he's willing to pay the price -- a price higher than even he, with his unique capabilities and all they cost him, ever imagined. A pulse-pounding chase through a dystopian America, "Rewind" won the Writers of the Future contest in 2002.

"Rewind," a short story, is also available as part of Space Magic, an award-winning collection of science fiction and fantasy stories by David D. Levine.
