Stranded On Earth — Anne Kane

Liisa's passion is books, the kind they used to print when humanity still inhabited Earth. The only authentic collection in the galaxy is located in a museum housed on old Earth. Needing a break from work, she came to Union Station to indulge in an orgy of reading. Of course, she didn't count on falling asleep in the library and missing the last flight off-planet before the winter season suspends interstellar traffic.
Jake is a sergeant in the Space Militia. . He lost the draw this year and stayed behind when Earth was evacuated for the winter. It's his job to make sure the mutant life forms spawned by the nuke wars don't break through the museum's barrier. He's resigned himself to a long, lonely winter fighting mutants and boredom.
When he discovers he's not alone on the frigid remnants of Man's home world, he knows he should be a gentleman and keep his hands to himself, but spring is a long way off and Liisa's charms are hard to resist.
