Recently I picked up a copy of The Ophiuchi Hotline by John Varley. I had always wanted to read it.
After a couple of dozen pages, I realized that I had read it, years ago. I then realized that I couldn’t remember how it turned out, and that I wanted to know. So I had to read it again.
It’s quite rare for me to read a book more than once. Generally I feel that there are more good books than I can possibly read during my life, so it would be sheer foolishness to re-read one. So for my own benefit, a memo to myself: You’ve read “The Ophiuchi Hotline” twice, you don’t need to read it again.
It’s pretty good. I’m not sure if it’s really worth reading twice, but it’s definitely worth reading once.
