It seems funny to call a steamy story about goddesses and demons in hell sweet, but that's how this struck me. It's a beauty and the beast story, except that in this case beauty feels pretty beastly too, and the both of them spend much of the story feeling insecure and wondering if the other could ever possibly like them. In this case, hell seems mighty similar to high school. There's kind of a cool twist at the end that leads into the "Lord of the Underworld" series, but no real need to read this one before it.
