When I first picked up _Stranger in a Strange Land_ I wasn't expecting much. I had read _Starship Troopers_ and _The Puppet Masters_ and thought they were O.K. But this book just blew me away. Not so much because of its science fiction extrapolations, but rather for how funny, intelligent and true the book rang. _Stranger..._ shows human beings through the eyes of one Valentine Michael Smith, a Martian with human origins. He is so child-like, so innocent, so funny and calm in every situation even though he has such awesome powers--it's amazing to read about him. Along with Gully Foyle, in _The Stars My Destination_ I think he is one of the best SF protagonists ever written. And the way he learns and evolves from the strange cast of human characters--I also really liked Patty and Jubal Harshaw--is wonderful to read. The ending is so unforgettable. And how Heinlein came up with such a cool word like grok I'll never know. Also, he brings the interesting concept of water brothers into the story, and shows how humanity should love each other without resorting to meaningless violence. Sometimes Heinlein gets a bit too wordy and some of his views about God and woman I find hard to swallow--I can see why this book is so controversial. But aside from those minor flaws, _Strange..._ is a great book to read not only because it is enjoyable by itself as literature, but also because it has the intelligence and audacity to pose such difficult questions and firm beliefs about humanity, God and our place in the universe when now such concerns are ignored by most current SF.
