For your reading pleasure:
Happy Birthday, Harry: We Have A Target and

ALSO, because I am a tres geeky fanboi, I was thinking today that if I saw a story where Harry Dresden and Vlad Taltos teamed-up, I'd probably plotz.
(Then, I thought about Vlad teaming up with Locke Lamora and Jean Tannen, and I DID plotz. Then, I thought about the Three Musketeers teaming up with Cyrano and Captain Alatriste, and plotzed halfway through the thought. We shall not speak of the Kirk and Sheridan team up, or the Matthew Gideon and Malcolm Reynolds team up.)
