Monster's Payment

I'm taking his daughter as payment, but he's the one I'm going to kill.***I knew monsters were real, but the ones I'd met didn't have horns and claws.When my father trades me to have his competition slain, I can't say it surprises me, but the creature I've been given to is a monster in the literal sense. I never would have thought fur and fangs were my thing, but when the monster promises to fill me with his seed, I find myself craving just that. He killed to have me, so who am I to deny him what he wants? ***This is the fourth book in the Monsters in the Mountains series but it can be read as a standalone.***
