John is a tired, world-weary angel. Moriarty is an ambitious, up-and-coming demon. They’re fighting over Sherlock’s soul. Sort of.
Highly creative and refreshingly novel take on the whole angel/demon thing. It’s also smart and badass and awesomely characterized and my only sorrow is that the author didn’t write an entire novel in this setting. Damn, I’d forgotten just what a great read this is.
