Sins of His Wrath by Zoey Ellis

Bound to an enemy who refuses to let her go.

Naya’s escape from the ruthless Alpha King, Akoro came at a devastating cost. Her people are on the brink of war, her kingdom stands vulnerable, and no matter how far she runs, the primal hunger between them refuses to fade.
It haunts her. Consumes her.
And when Akoro finally comes for her, his ultimatum is as cruel as the man himself: surrender or watch him tear her world apart.
Desperate to stop the bloodshed, Naya makes a daring offer—one that should satisfy any ruler with a shred of reason. But Akoro is no reasonable king.
He is as vengeful as he is possessive.
And nothing will distract him from his need to claim her.
With each clash of wills, their desire turns sharper, darker—an intoxicating struggle neither can escape.
Naya refuses to yield. Akoro refuses to let go.
Can she save her people—and herself—or will she break under the brutal will of the mate she can never outrun?
