Purchased by the Oni Lord: A Monster Fantasy Romance by A.M. Matsuda

Miyuki had days to live left on the clock. If she wasn't purchased within the next few days, they would kill her. Manual labor or servitude were the obvious routes one could take when they were gaunt and not as beautiful as so many others. So her hopes of finding someone were impossible. Until a cloaked figure buys her for the highest price anyone has ever sold for. Her only problem? It's to the Oni Lord, a demon known for his cruel acts against human villages. And he's calling her his mate... Perfect for fans of Ice Planet Barbarians and Elise Kova
