I had planned to spend an evening doing something profitable, but in the end I just read The Man in the Maze by Robert Silverberg. This was a great book about meeting aliens and feeling very bitter. I now want to live in an alien maze -- it is the thing to do. It reminded me a bit about Gulliver's travels, where after one final voyage, he can no longer stand human beings.
The prose was crisp and simple, but I liked the big ideas.
