I don't read very much. The best novel I ever read was 'The Executioner's Song', but that was some kind of second hand journalistic impressionism by Norman Mailer via Larry Schiller. I liked the part when Gilmore's autopsy is described. That's the climax. They peeled his face off, I remember.
I read a real good non fiction book recently titled 'The Red Hourglass'. I forget the author's name, but it is a series of slightly dark and grostesque naturalist essays about various animals: pigs, dogs, brown recluse spiders, praying mantids, black widows...It is extraordinarily beautiful.
