I love the Dresden Files. They keep getting better! I'm on Small Favor right now. Harry is one of my favorite characters; he's hilarious!

Another fun series is Julie Kenner's soccer mom/demon hunter books. The main character was sort of like Buffy in her youth, but retired to be a stay-at-home mom. Then, in her late 30s, she started fighting demons again. The books are very funny and have lots of action.
