This is one of the fifteen that hit the sweet spot.
As I look back over my five hundred plus posts, I find Heinlein mentioned more than any other writer. I’m not going to repeat all that I have said, but I will provide links for you to see for yourselves.
You might think RAH is my favorite, but he isn’t. That would probably be Zelazny. When I was new to science fiction, in the fifties and sixties, it would have been Andre Norton. However, Heinlein is the one I most enjoy reading. His prose sings, but in an odd kind of way. He is like a weird uncle who sits by the fire telling lies and funny stories, occasionally laughing out loud at his own jokes, and getting serious just often enough to keep from looking like a clown.
But he does it so well.
Heinlein has been through three stages as an author. At first he was the master of compact, carefully plotted works, both short stories and novels. That was what publishers demanded at the time and he produced some masterpieces. I reviewed five of them in one post.
Then came Stranger in a Strange Land, his most popular book, and a dud, for my taste. That was the start of his inflated period, which continued until his death, as his books got longer and more discursive. He gets a lot of criticism for long windedness, and deserves all of it, but some of those works are my favorites.
Alongside his early work, Heinlein produced a number of juveniles (as they were called then) and some of them were of top quality. I reviewed several briefly, just this month. At the end of his list of juveniles is the book that Scribners rejected, Starship Troopers. It is another favorite of many, myself decidedly not included.
Actually, I’ve talked about RAH more than I had realized. Maybe I need to give him a rest for a couple of years.
