Rachel grew up in a world ripped apart by civil war. Alphas, genetically superior humans, wrested control of the western nations from the governing body twelve years ago. In the wake of the war, the Alphas struggled to remember the old traditions which had bound them to society. There are cracks in the new foundations, places for bad men to rule and for innocents to fall through.
After trying to care for her unstable mother, Rachel is picked up as a lawbreaker and slated for claiming or execution by an Alpha. In walked a stranger named Morgan. Unwashed, unshaven, flip flop wearing, unrefined Morgan, who all but kidnapped Rachel to take her home to his Master to be his breeder.
Neither planned beyond that. Alphas tend to just let things happen, and Rachel didn't really expect to live through the day. Maybe a plan would have made things run smoother.
