Wow - I will be honest and admit I was terrified to read this, esp since I'm fairly protective of Luna as a character and feared it might be some sort of bizarre Fenrir/Luna love story. I am happy to discover it wasn't and that this was an incredible character study of Greyback. Creepy as hell, but that's the point. I loved the insights into his character and background (would that the actual books gave us more than a 2-dimensional baddie in Fenrir). Great story!
