Set in Robert A. Heinlein's Future History universe, REVOLT IN 2100 includes "IF THIS GOES ON--", his novella "Coventry" and story "Misfit", his Future History charts, "Future History Letter Essay" and the author's "Concerning Stories Never Written" Postscript. "IF THIS GOES ON--" The Second American Revolution unfolds in the course of this novel where John Lyle, West Point graduate and now a guard at the Prophet's stronghold, comes to realize that "secrecy is the keystone of all tyranny. Not force, but secrecy . . . censorship." After he joins an underground movement to overthrow the U.S. government, John learns much along the way about courage, subversion -- (a fellow conspirator tells him, "There is magic in words, black magic--if you know how to invoke it") – and sacrifice. "Coventry' takes place years after America's Second Revolution and posits a benevolent but strongly monitored new society, with its own rules and surveillance arm."Misfit" concerns a young genius who averts disaster in a mission to bring a small asteroid closer to Earth. The author's essay about Future History stories he *won't* write provides an entertaining look at Heinlein's richly imagined world.
