His Darkest Devotion by Addison Cain

In the dark embrace of their bond, Lorieyn belongs to Cyderial in every sense—except one. She does not love him.
As war threatens to tear their world apart, the terrifying general will risk everything in the battle to conquer her fears and draw her to him. To prove himself worthy of possessing her mind, body, and soul.
Teach her that she will be fulfilled kneeling at his feet.
And in exchange for her love, he will give her everything.
But first, he must break her heart.
Expose the dark world for what it is, and show his darling Lorieyn why his path is the only way—for the humans are not what they appear.
He will stop at nothing to earn her affection—even if it takes a thousand years. Even if he has to burn the world to ashes…
Dive into a world where love is a dangerous game and surrender is the ultimate victory. His Darkest Devotion, book two in the Insatiable Instinct duet, will leave you breathlessly in love and dangerously obsessed.
