If you weren’t familiar with the books and essays of J. Daniel Sawyer until recently, join the club.
A prolific writer of more than 31 fiction and nonfiction books, including several in the sf and mystery genres, and 24 short stories – not to mention being a huge fan of Robert Heinlein – Sawyer deserves to be much better known by libertarian sci-fi fans and LFS members.
That’s especially because Sawyer has written two books about Heinlein and one of his nine novels is explicitly structured and billed as a “Heinlein juvenile.”
