Shields of Mars

I read GW's new short story, "Shields of Mars" (in the June 2002 MARS PROBES anthology from DAW) last night. A straight Hard SF tale about engineers tending a nuclear reactor on Mars, but with a wonderful transformative twist at the end. Very shrewd stuff (and the rest of the anthology, I should add, is pretty good too--Aldiss, McAuley, O'Leary, Baxter, Moorcock, McDonald...). Best, Nick.
