My boss loaned me Look to Windward, and told me I had to read it. He was right, and as soon as I found some other of Ian M. Banks’s books, I bought them. He also reminded me that Iain Banks is the same person, but not the same author. That author writes “real literature”, not genre.
I can read and enjoy “real lit”, but prefer SF. If I need seriosity, I’ll reread Dhalgren.
