Highland Secrets. Dragon Lore, #1

Furious and weary, Angus Shea wants out, but he can't stop the magic powering his visions. The Celts kidnapped him when he wasn't much more than a boy and forced him to do their bidding. He's sick of them and their endless assignments, but they wiped his memories, and he has no idea where he came from. Arianrhod prefers to work alone, mostly because she harbors a dirty little secret. She's not exactly a virgin, and she'd be laughed out of the Pantheon if the truth surfaced.
Despite the complications of leading a double life, she's never found a lover who tempted her to walk away from her fellow Celtic gods. That comes to a crashing halt when she meets Angus in Fire Mountain, the dragons' home world. Attraction ignites, hot and so urgent Arianrhod's carefully balanced life teeters on the brink of discovery. Angus is everything she's ever wanted, but he's far too close to her Celtic kin to keep her secret safe.
Angus wants her too, but she's a Celt. He's hated them forever, and she's part of everything he's lain awake nights plotting to escape from.
