My father saw fit to throw me to the beasts as a means to reclaim the lost lands.I was the bargain for a better future for the last human kingdom, but I felt more cursed than blessed. Forced into training to please a beast and ensure I was fit to be his wife.I dreaded the day I'd wed the Monarch and be treated no less than human meat. I've heard stories about him, and they are far worse than any combined. They call him a mindless beast, merciless, the ultimate feared being in the entire realm, and the terror that bested the vampires in war and ended it under his rule.My future was bleak.But when the day arrived and I set my gaze on the beast I'm meant to marry... I realized Drevon Balthar was unlike the rumors; they didn't tell the whole story.
