Peaceful rest, Mr. Ballard.
His novels included the World War II story Empire of the Sun and Crash (made by David Cronenberg into a film); I've read and enjoyed Ballard's Hello, America, his 1981 post-apocalyptic novel about a mostly abandoned United States (nothing but desert east of the Rockies, something else west of them) and an expedition back to the continent. This is the novel with a psychotic man who's building a new empire out of Las Vegas and calling himself "President Charles Manson." Not quite a comedy, but often darkly funny. I've been meaning to read more Ballard.
