Books finished: Halting State by Charles Stross (thanks nihilistech!) Really delightful story with plenty of off-the-cuff references to geek culture now and past. Raises some interesting points about immersive computer-mediated overlays. Recommended.
I know there were a couple of other books in there as well, but clearly they didn't make much of an impression, so I won't worry too hard about trying to dredge up their names.
