James Fisher's memories of Earth are distant, replaced by the harsh realities of life on the planet Castor. As a "Half-Adapt," James is one of many who were biologically engineered to survive conditions on Castor - and to labor for the benefit of the ruling class. Indentured to servitude, James has no way to defy or escape the severe caste system... until he meets Vidal Centa, his master's nephew. The draw they feel toward each other is instant, powerful, and maybe even enough to move beyond the unyielding regulations of their society. But not everyone blindly accepts the absolute power of the oligarchy. The Independence Society fights for freedom and equality, and since James shares in their ideals, he joins their ranks. Soon he's faced with an impossible decision: continue the fight against the oppressors or choose the love of the young man who embodies everything the Society loathes. With a looming conflict threatening to tear the planet apart, James fears he cannot continue to fight if he wants to keep his relationship with Vidal.
