I admit to having a pro-Heinlein bias—he is my favorite author—but, frankly, he deserves it. Robert A. Heinlein is possibly the most influential science-fiction/speculative-fiction writer in history, and I believe he is unequivocally the best. I have enjoyed every one of his novels that I have read (more than twelve so far), and his work never fails to make me think.
