I was commenting on another blog earlier, where Robert Heinlein's name was mentioned. Later, while I waited outside for my daughters' school bus, I found myself reminiscing about one of his books, Have Space Suit, Will Travel. It was the first sci-fi novel I ever read.
Even after more than thirty years. I can still remember the story line, though I won't spoil it for anyone here.
How about you? What was your first sci-fi novel (or short story)?
