After the Great Destruction decimated the world, science is the new god. Geneticists rule, instituting a DNA-based caste system in their effort to restore the human genome. As a Zed, Will's a virtual slave who isn't allowed medical care. A tragic accident has left him crippled, awaiting death. Just before his time is up, Malcolm, an enigmatic Alpha with two differently colored eyes, sweeps in and buys him. Will becomes part of a family of freaks-other damaged Zeds who should be dead. Life seems ideal until Malcolm makes a request that could change Will's life. Malcolm harbors more secrets than his Zeds could imagine. His attraction to Will unravels his carefully cultivated control, and one secret escapes: he craves pain, not just as a sexual release, but as a way to atone for his past. Will may be the one person who can give him what he needs if Malcolm can only allow him into his heart. As they struggle to build trust, each secret Malcolm reveals threatens their relationship. In the end, their desire for each other may heal both men if they can unlearn the lessons of the past.
