Do I love Harry Dresden? Yes I do. Why? Well, that's a bit more complicated. But let me give a quick example from something that happened in the latest book, Cold Days, that might help explain. 
 At some point, Harry is running from bad guys. Folks are hot on his tail and he's got to get out there. In fleeing he runs smack dab into a man waiting for him with a baseball bat. Before he can react he's being bludgeoned. 
 And then Harry begins to tell us (the reader) how awesome he is at getting his ass kicked. He explains that if someone can kick the ever loving crap out of you, and you do everything you can to avoid it - well, then you become a bit of a coward AND you don't learn how to take a beating. 
 So, his philosophy is to let them know that they might be able to whup you, or even kill you, but so what, that isn't going to change anything about how he acts around you. Of course, having that attitude leads to a lot of beatings in life. And as such, he's gotten great at learning how to be beaten severely and still minimize the damage inflicted - something he'd never have gotten good at without all the practice. 
 He's filling the reader in on this in-between licks with the baseball bat. Not only does a moment of the book like that make for entertaining reading, it's also brilliantly making me like the character that much more. Making me root for him. 
 Yes, this series is becoming so self-referential that even as a pretty big fan I'm starting to get confused about things. But it still has as much charm as it ever has, and there is still this sense of momentum that is building with each installment. I really believe Jim Butcher is taking me somewhere with all these novels. He's telling a much larger story here. 
 Can't wait for the next one. In fact, he is one of the very few authors that has produced works that I have read over again. If I get anxious between installments I might just reread the series - that way maybe I won't get confused over plot points in the future that hinge on things that happen in earlier books.
