The Traitor by Abigail Owen

Decades ago, rogue dragon shifter Rune Abaddon took a stand against the decaying, corrupt systems governing their people. He now uses his bad-ass reputation to protect the innocent as it all comes crashing down. But he’s pushed the limits one too many times. His hideout is destroyed, his few allies are scattered and hiding, and the Alliance has placed a dead-or-alive bounty on his head, making him the most wanted dragon in the western hemisphere.

And then the most enticing woman he’s ever met barges into his mountain, demanding an audience.
Hadyn Reece’s future was ripped away long ago. The man fated to be her mate was murdered alongside her parents before Hadyn was old enough to be turned, leaving her to be raised and trained by her dead mate’s parents in the dragon shifter world. Now, the Alliance has come for the only family she has left. It’s a good thing she was raised by dragons, because the only one who can help her save them is a traitor she’d be smart to fear.

Especially when his dragon decides she’s theirs.
