I‘m not religious but I am a fan of vampire stories, and this one was really quite unique. Basically, Christianity saved Raven‘s soul, and he gradually (through good deeds and faith) became human again. Physiologically, not sure that makes a whole lot of sense but you know. I was pleasantly surprised that the romance between Raven and Calandra was so chaste throughout. I think Luco turning out to be a vampire actually dampened the story a bit.
