Rhani by Ruth Anne Scott

She couldn’t believe what he turned into…
When a wild pig gores Moira Flannery in the stomach and leaves her for dead, Moira regains consciousness in the red dragon’s nest on a lonely mountaintop outside Harkniss Keep. What’s he doing to heal her? His touch sparks her deepest desires and transforms her into something she never expected. Her growing love for Rahni Harkniss, oldest son of the dragon-shifter Clan Harkniss, turns Moira against everything she knew and understood.

Rahni is the red dragon, and the heat radiating off his skin sparks a forgotten well of lust Moira doesn’t need to understand. The Allies withdraw their research teams to escalate their invasion. Rahni and Moira flee to Prowiss Keep and Rahni’s maternal relatives for safety, but hidden dangers threaten Moira and her new love.
Just when she thinks she’s found happiness, she gets sucked into a world of intrigue, passion, and unstoppable destiny that could destroy everything she holds dear…
