The Cyborg's Queen

While my friends have been forced to marry cyborgs, my father has prepared me to take the throne alone-no husband needed. Unfortunately, that quickly changes when my father falls victim to an assassination attempt. To hold on to power, I need a husband, and I need him now. Preferably someone who is big, strong, and-ideally-ruthless. The cyborg named Killer seems like the perfect candidate, but he hates humans with every fiber, screw, and circuit board of his being... Historical romance meets space.* Princess meets cyborg.
Completely over-the-top with all the best champagne flutes, fanciest ball gowns, and shiniest crowns you could wish for.   (*No actual history or science involved.)
