Alien’s Fire by Lynnea Lee

VIVIAN
What does it take for a chubby, socially awkward girl to get all the attention? Easy peasy. Just get kidnapped from Earth and thrown onto an alien planet. Since landing here, I’ve been fought over by every single alien I’ve met. Even the local wildlife want a taste.
The one who has me now is terrifying. He’s huge, red, and looks like a demon—complete with a pointy tail! His touch does strange things to my body, and that’s even worse than being scared.

COAL
All I wanted was to get the human female off my mountain. I’m not interested in having a mate; I’m very happy living alone. But the more time I spend with Vivian, the more I realize I can never let her go.
What starts out as a chore to get back my peace and quiet becomes a race to win my mate. I might not be the warrior I once was, but my mate makes me whole, and I’ll do anything to keep her.
