Cheated out of his exit from the Tribute program, Kai Mexr is forced to return as a trainer for one more year. His trainee, Aled Price, is an idealistic Mitan patriot who Kai struggles not to loathe on sight, and who seems up for any challenge Kai sets him. As Aled learns to give up control and endure the program's worst, Kai is drawn into an intense sexual game that leaves him wanting more. But then Aled must fulfill his duty as Tribute. He must endure the Ungrich -- or die. When Aled returns, it takes Kai's ruthless presence to pull his trainee back from the brink of madness. Surviving the Ungrich makes Aled doubt his blind allegiance to his planet -- and to everything else he'd never thought to question. But with Kai at his side, Aled finds a new cause to believe in. And with the help of master trainer Akran and his partner Anna Lee, Aled and Kai forge unbreakable allegiances of blood, sex, and love that could save the entire planet from the Ungrich for good.
