Blurb:
Submission isn’t an option—it’s a full-time job.
A Men in Space story.
Humiliated by the betrayal of his former Master, Lieutenant Benjamin Kraft will do anything to bring the drug czar Tazu to justice—anything but kneel again. Forget passion too. He’d rather risk daily grow-op raids. Then, just when Tazu is finally within reach, an ambush wipes out Ben’s entire squad and threatens the life of his partner—a partner he never realized he cared about, much less loved.
As a member of a former slave race known as starlings, Adam’s speed and strength make him a valuable asset to the police force even as his blue skin inspires prejudice and derision from the other officers. Ben’s always been able to look past that, so what’s changed? Suddenly his partner is rude at every turn. Ben may try to get rid of him, but too bad; Adam won’t be scared off. He has his own reasons for wanting to bring Tazu in, and he’ll do it even if it means putting Ben in his place.
Even if it means acting as Ben’s Master on their next mission: an investigation on a planet where sex is everywhere, and where whips and chains are the norm…
