I've just finished Ken Kalfus' A Disorder Peculiar to the Country, a black comedy about a divorce from hell, set in NYC on 9/11 and the ensuing months. For the first two-thirds I liked it, though sometimes I had to make myself pick it up, what with the themes being what they are. Often very dark and painfully funny. But it turned too episodic and scattershot, didn't build quite as I would have expected, and at the end took a sharp turn into a sarcastic historical fantasy ending that is the sort of thing I ought to like, but that I didn't feel built on or went with what had come before. So the potential effect, for me, was lost.
Next, Alexander Waugh's Fathers and Sons.
