In a future ruled by an exploitative caste system, Malcolm, a member of the highest caste, and his lover Will, a member of the lowest caste, work with their family to change the world in which they live. Will's found the solution to their problems: a way to infiltrate the Department of Genetic Integrity and hopefully find the truth they've been searching for. But just when victory is in their grasp, tragedy snatches it away.

Devastated, Malcolm seeks revenge for the horrors inflicted upon his family, but each of his victims draws him further form the goal he's spent his whole life working toward. Will is left to shoulder the burden of leading the movement for change, but he can only do so much. To pull their family through the darkness and toward a brighter future, Malcolm and Will must rely on the unlikeliest of allies—an ally who may prove even more dangerous than the enemies they face.
