Qorth

It is the year 3017 A. F., and Cameron is a neo-cowgirl living contently on her farm beside the sea in the dangerous, post-apocalyptic deserts of Arizona, a world where Earth has for the most part been swallowed by the rising sea levels after what became known as The Great Flood. Cameron survives the harsh life in the Outer Zone by casually shooting those scavengers who threaten and bully her. With biker gangs roaming the desert sands, the world has made her rough and ruthless, and it is her rough nature that nearly kills the gentle and compassionate alien who washes up near her farm.
Through Qorth's love, Cameron learns to soften her frayed edges. But will Qorth learn to engage in the casual cruelty that is her only key to surviving Earth? Can beautiful things survive a cruel world? --In case the title was misleading, this is the story of Qorth. She was an alien, but she was more normal, more boring, more goofy, and more ho-hum than any human I'd ever known .
