I like "The Crossing" the best of McCarthy's novels. "The Road" is the most depressing "after the fall" novel I've read. And I've read a bunch. Kinda wish I'd skipped it, but literally couldn't put it down. Horrified fascination.
I've probably mentioned Allen Furst's pre-and-WWII spy novels before, but I really like them. His latest isn't the best; either he's running out of gas or I am. My favorites are "The Polish Officer" which really gets at the "glories of war," and "The Foriegn Correspondent" which would make a decent textbook on how fascists operate. Some of his earlier books make it clear how communists operate. Same ways.
