As I mentioned, the Robot books by Asimov are comfort reading for me — have read them a bunch of times, they never get old. And The Naked Sun is my favorite of them. It’s about a murder on a planet where human contact is incredibly limited — a sci-fi twist on a locked-room mystery. Fun book; will read it again, no doubt.
