Wickedly They Dance by May Sage

The world has learned to fear vampires and forgotten a greater threat.
Before the bloodsuckers rose, the gods had perfected one race of predators.
And they’ve chosen their prey.

Avani was raised in another pack, another world, away from the secluded werewolves of Oldcrest. But the shadow that has followed her every step since her first shift has forced her into exile.
Oldcrest is the only place in the world where she’s safe. She won’t let anyone take it away from her. Not even her own kind.

As threats surround the territory, everyone demands Alexius’s allegiance. In his hundreds of years, he’s lived without bending the knee, and it won’t start now.
But when a wounded, hunted wolf crashes into his life, the healer in him can’t help lending a hand, although he knows touching a female of the royal pack marks him for life.
As an enemy.
Or as an alpha.
