Query: Hell's bells, a scary ride

"Hell's Bells!", as Harry Dresden would say. Great fantasy, truly scary demon/evil stuff, humor to help relieve the tension, and one of the best love scenes I've read in years. Tender, lovestruck, broken-hearted Harry...You can't help but like him. And did I mention the wizard lore, action, religious undertones, a likeable mob boss, a spirit named Bob, and some vampires thrown in? Thanks Mr. Butcher, you write fun stories!
