I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
Earlier this year, I read the short story version of this and decided that I needed to read the full treatment. I had to request it through interlibrary loan, as neither of my libraries has it and I couldn't locate it second hand.
So far, its very similar to the short version, but I'm remembering why I requested it.
If you could live happily, indeed joyously, without sleep, what would be the effect on society? Especially those who still need sleep?
