I have always thought of Heinlein as having written two original books. The first part of _Stranger in a Strange Land_ was one of them, then pick the second part or any of his other books for the other. I really tried to look for originality in his others that I read, but aside from names and settings, I just didn’t find any. I wish he had written more books with the freshness of SiaSL.
