Teran by Ava Ross

The alien she’s hot for seems to hate her. But when they touch, sparks fly. Will their growing love survive a dangerous quest?

Emma: I’m pretty sure Teran hates me. Why else would this scarred dragon warrior avoid touching me, talking to me, or being around me? Yet when we’re sent on a quest to find a long-lost cache of precious stones that could save the kingdom, I’ll be flying for weeks in his arms. I have to guard my heart. Otherwise, he’ll break it.
Teran: I am crazy about Emma, and I long to touch her, to bring about the Torrent–the ancient Driegon mating ritual. Our quest will throw us together, and it will be torture to hold myself back, but if I give in, I could endanger her life. But when rival factions attack, determined to keep us from finding the stones, I’ll do whatever it takes to protect her.
