Beautiful Darkness: The She-Demon's Alpha (Into the Darkness #2)

"No one can touch what is mine."

The only thing Alpha Adan Stone Robinson cared about was finding a female who could give him an heir. But the moment Lucy came into his life, everything changed. He wanted her more than anything, and finding out she was half-demon was never a problem—until her father, the Demon King of Kalmerus, showed up and took them all to hell.

With a mate and an eternal life bond entwining Adan and Lucy's lives, they were bound to have the same fate—either they make it out alive from hell or die together. But will their love be enough to escape the King of the Underworld, or was their bond a mistake of the gods from the very beginning?
