Voight's Plaything

I need a protector who has no problem breaking a few interstellar laws for me. Since I'm smart enough not to hang around dubious space stations, I need to buy a prison inmate by paying the bounty that was put on his head. Tankol is big, has an arm made of metal, and looks mean for my purposes, he is perfect. However, the eight-foot tall alien doesn't have the slightest desire to obey me. . . This is a dark sci-fi romance novella. Standalone. HEA. No cheating.
