Just finished 1635: Papal Stakes, Ring of Fire III, and am halfway through 1636: The Kremlin Games. Papal Stakes was one of those novels in the series I had to read to stay abreast of developments but it was about crap I really don't care about-theology and the damned Italian part of the 1632 Universe. Ring of Fire III was a mixed bag. Kremlin games was a compilation of the "Butterflies in the Kremlin" stories from the Grantville Gazette, if anyone has read those. Great little tale thus far. Once I'm done, its on to Angels of Vengeance by Birmingham.
Btw-anyone looking for a good book(s)-check out Michael Z. Williamson. Helluva good author. Oh, and Redshirts was very disappointing, IMO. I preferred Night of the Living Trekkies, myself.
