That's one hell of a cover.
I finished Cryoburn (and thus the Vorkosigan series) a few days ago. Was pretty satisfying overall.
Just started Old Man's War, three chapters in. It's a good read so far, although half dozen of the senior citizens Scalzi's thrown at me speak with almost interchangeable snark/scientific speculation. He wrotes both pretty darn well, though, so one will see.
Hate to double post but missed this at first. Scalzi does good-he's VERY reminiscent of Heinlein in style. Old Man's War was like a breath of fresh air in a stale market when it came out...
