Devolose by Alana Khan

Her friends say he’s the devil. But he might be her savior.

Devolose and Tawny have been rescued after three years together in the emperor’s dungeon. Every day he was forced to inflict pain on the Earth woman he only wanted to protect. How could he not develop feelings for her when they’re connected in so many ways?
But how can they trust feelings forged in captivity? The more he pushes her away to protect her, the more determined she is to stay at his side. After decades of slavery, the emperor took far more than his soul. Can half a male satisfy a complete woman?
