After Grif died, he became an angel tasked with shepherding newly killed souls to the afterlife. But a moment of mercy threatens the angels' secrecy, and as punishment Grif is forced to become human again. He can return to his celestial form only after he watches Katherine Craig die. But Grif finds her imminent death intolerable, and is clearly going to try to circumvent fate. I don't know--I only got 14% of the way into it. I just didn't care about Grif or the oh-so-beautiful Katherine. The writing is fine, but it didn't pull me in.
