I finished All Clear yesterday, the second half of Connie Willis's 2011 Hugo Winner. I found it slightly less good than Blackout - there was a really long section early in the second book that I knew could never amount to anything because it was early in the second book - but overall I really enjoyed it. Maybe it was about one-and-a-half books' worth of story, rather than two, but I'm not unhappy that it won the Hugo.
I'm not sure what's next. Probably A Man Lay Dead by Ngaio Marsh, in paperback.
