Query: As Bob would say, 5 stars, 5 boners, what's the difference?

No I'm not a perv. But if I were Bob, that's exactly what I'd say. This is the best Dresden Files novel out of the first 6, and the rest get even better. This has very heavy emotional stuff, though Death Masks had even more.The action is high octane, the dry humor's not gone, and the role play of the characters is amazing.'Love this book!
