Sorry, it made sense in my head.
Right, exactly. Don is a noted Heinlein fanatic.
Just what you thought about the book after reading it for the first time. FWIW, if I had to recommend an introduction to the man's work, Number of the Beast would be near the bottom of list. Hope it doesn't sour you on him permanently. I think he's great. Perhaps not the most sterling prose stylist who ever put pen to page, but he can tell the hell out of a story.
Heinlein's not for everybody, but those who like him tend to like him a lot. I'd heartily recommend his juveniles, particularly if you are a juvenile.
Pretty much
anything he wrote between 1950 and 1967 is a good read. There's lots of good stuff both before and after as well, but that was his best work as far as I'm concerned.
