King David’s Spaceship was written by the, alas, late Jerry Pournelle; and if you have not read it, it is an excellent story that manages to incorporate espionage, medieval-era combat, and interstellar travel into a seamless mass that only looks easy when you’re not trying to duplicate the trick. Not his best-known work, but I think that I read this before I really got into anything else that Pournelle wrote. Go check it out; I wonder where my own copy is.
And so, adieu to Golden Age and Other Stories.
