Run Little Omega by Lucy Auburn

She ran to save another. He’ll destroy everything to claim her.

In the borderlands, the crimson moon rises once every seven years, bringing with it the Wild Hunt—twenty-one brutal days where fae alphas hunt human omegas for breeding. Most don’t survive the chase. Fewer survive what comes after.
When Briar’s best friend Willow is selected as this year’s tribute from their village, she makes an unthinkable choice. Using forbidden magic to disguise herself as the dying girl, Briar enters the Hunt in her place, armed with nothing but a blacksmith’s strength and an iron will to match.
Her plan is simple: draw the most dangerous alphas away from weaker prey. What she never expected was to catch the eye of the legendary Winter Prince himself—a fae alpha who hasn’t entered rut in seven centuries of existence.
Until now.
As Prince Cadeyrn systematically eliminates any alpha who dares pursue her, Briar discovers a terrifying truth: she isn’t just running from him. Something primal within her is running toward him, drawn by ancient magic that transcends the court’s brutal breeding program.
When his bite claims more than just her body, Briar must choose between the freedom she’s always fought for and a bond that will either destroy the fae courts—or transform them forever.
The Hunt has begun.
And this omega isn’t the prey they expected.
