I've read The Course of the Heart. It seemed like one of those anti-books that try to subvert the reader's expectation of a plot, message, or point. I suspect these books are best enjoyed by some kind of anti-reader.

I've also read The Pastel City, it seemed like very unremarkable sci-fi.

It's a shame, because he also had one of the best book titles ever: The Sunken Land Begins to Rise Again. If such a book was written by anyone else, I'd jump on it instantly. As it is, I avoid it and prefer to imagine how awesome a book with that title could be.
