When a distant planet's ownership is in dispute, conquering aliens turn defiant human males into pampered sex slaves.

Stuart McKay, a young man always on the sidelines of life, has been reinvented as Mac, the beloved pet of an alien navigator. At first an unwilling captive, he's now fallen hopelessly in love with his master. Narith is Mac's perfect fantasy lover, so much so that Mac does not hesitate to join him on a frightening trip to the Travian home world.

Narith is a brilliant young officer from a lower caste family who has risen quickly up the ranks. He's also climbed the social ladder by making an advantageous mating. A tragedy has him hurrying home to mend familial fences and fend off the predation of another male. All the while, he tries to tamp down his growing feelings for Mac, yet cannot bear to leave his pet behind.

Mac and Narith's relationship is tested by family tensions and brought to the breaking point when Narith reluctantly agrees to share Mac with another male. Mac is devastated by Narith's seemingly cavalier treatment, while Narith is surprised to realize he's jealous of another male claiming Mac's body. But more than personal feelings seethe beneath the veneer of domestic harmony and, as trouble bubbles to the surface, the fate of Mac's and Narith's very lives is at stake.
