Eden's Deliverance. The Eden Series, #4

Fate is the life we're given. Destiny is what we do with it. Captured as a child and forced into slavery by the Rebellion's leader, Brenna Haven was raised in near isolation with the utmost cruelty. She knew nothing of kindness or compassion until Fate orchestrated her rescue. Finally free, she wants nothing more than to return to her home. To reconnect with her human family and live a simple, quiet life.
But her newfound powers demand an entirely different future. One fraught with danger and a terrifying role in an ancient Myren prophecy. A battle-hardened warrior and sworn bodyguard to the king, Ludan Forte wields a powerful, memory stealing gift. But his skill comes with a price. A torturous burden he's hidden since his awakening over a hundred years ago. He never dreamed he'd find relief, let alone be tempted to forgo his vows to the king.
Yet in Brenna's sweet beguiling presence, the weight he bears is lifted. And when her role in the prophecy threatens her life, he'll stop at nothing to keep her safe.
