A young woman's decisions decide an escaped clone's fate, and may decide the fates of all clone-kind.

Crippling anxiety forces Harper to maintain an attitude of indifference about most social issues. After her mother dies at the hands of her human-supremacist father, Harper gathers clues that her mother wasn't who she seemed to be. When her mother's secret lover arrives at her door, hunted and suffering from dehydration in the Texas heat, she discovers a side to her mother that she never knew. She should send him back as the law requires. To do that would mean his certain death. Harper must shepherd the refugee to freedom while hiding from Emergent Biotechnology and their ruthless bounty hunters.
