The world has become a harsh, bleak place. Men seek work where it's needed. The only safety working in the outer reaches is if one has the protection of a crew. Curt doesn't; he's solo.

But Curt's human -- he needs sex. Being tied up makes for some very curt courting, but to Curt's surprise, it might well end in love.
