Moonseed

It started the night Geena and Henry broke up.
As if to commemorate the end of NASA's golden couple, our neighbor planet, Venus, exploded into a brilliant cloud of dust and debris, showering the Earth with radiation and bizarre particles as big as bacteria - wiping out all the crops and half the life in the oceans, frying the ozone layer, forcing survivors to wear protective suits on city streets.
Days later, a few specks of moon rock from the last Apollo mission landed on a lava crag in Scotland. That was all it took. The ground itself began to shimmer, forming into spreading pools of luminous, almost liquid dust.
For what has demolished Venus, and now threatens Earth itself, is part machine, part life-form: a ten-dimensional superstring nanovirus that literally eats rock, transforming it into liquid, and then into molecule-sized black holes that devour the very fabric of space-time.
NASA "rock-jockey" Henry Meacher and his Japanese colleague, Blue, race to cut off the virus and save what is left of the Earth. Meanwhile, Henry's ex, Geena, straps in with a Russian cosmonaut for a daredevil Moon voyage, ultimately reuniting with Henry and searching for the lunar ice deposits that night make possible the greatest evacuation since Noah braved the Flood.
