The Epicenter

Hal's got a dream job, making exciting advances with cutting edge technology. True, he's complicated matters by starting up an affair, but can you blame a guy who's stationed on a barren planet several light-years from his family? The developments he's seen with nanoscale robots and their impact on cellular growth is worth the sacrifice and risk.
At least, it was until the risk made itself all too clear.
Hal was attracted to his coworker because her brilliance equaled his own. Now that their lives are at risk, will that intelligence be enough to save them?
