Lord of the Fading Lands by C.L. Wilson — book slip

Once, the majestic Fey King Rain Tairen Soul was a legend, driven wild with grief over the murder of his beloved. Now, a thousand years later, a new threat draws him back into the world, and a new love reawakens his heart.

Ellysetta, a simple woodcarver’s daughter, calls to Rain in a way no other ever has. Her soul beckons him with a compelling, seductive song, and no matter the cost, the wildness in his blood will not be denied.

As an ancient evil regains its strength, threatening doom for Rain and his people, he must claim his truemate to embrace the destiny woven for them both in the mists of time.

First in the Tairen Soul series.
