The Lost Fallen by L.C. Mortimer

Serenity cut off her wings to be with the man she loved. Then he died, leaving her alone, leaving her mortal, leaving her human. He died, leaving her without hope, but she found something to keep her going. She found a world she could lose herself in to deal with her pain. She found a world where anything goes as long as you can paint it, as long as you can draw it.

Wrath didn’t want to be cast out of hell, but his mood swings were too much even for the Lord of Darkness himself. When Wrath finds himself stranded on Earth, he has to find a way to deal with both his attitude and his newfound humanity. Someone suggests he sign up for an art class, and Wrath doesn’t have anything to lose.

When he meets the instructor, he immediately recognizes her as a lost fallen. She’s one of the angels who left: one of the angels who walked away from heaven for a chance at something better, a chance at something greater. Serenity doesn’t seem to know who – or what – he is, but she begins to show Wrath that sometimes, love finds us in the most unexpected ways. When an impossible force threatens to destroy Serenity’s very existence, Wrath is forced to make a choice. Will he continue to let anger destroy his soul? Or will he walk away from it in order to save the woman he loves?
