Wow I'm amazed that everyone likes Stranger in a Strange Land so much. It was a really good book but I like two of his others better. Podkayne of Mars was my second favorite; i really like the main character's brother
. and my favorite was JOB: a Comedy of Justice. I like all the twists and turns in that book, as well as how he makes out Satan to be the good guy and the one willing to help Alex. It's very different from the books of this ilk, and I like it a lot.
