Blurb: "A Robert A. Heinlein classic reissued with an all new celebrity forward by noted Heinlein biographer Bill Patterson and afterword penned by three-time award-winner for fan writing and science fiction scholar John Hertz.
It's a cross-time fight for freedom as a family retreats to a bomb shelter during a nuclear attack--only to emerge hundreds of years in the future, thrown forward in time by the blasts. Their lifeboat ethics rule as they struggle to survive... until they're discovered by up-time humans, the survivors of the apocalypse. These survivors are of African descent. Down-time humans--in fact, all of the European-descended--are held guilty for the state into which the world has fallen and designated as automatic slaves. The only escape is to find a way back down-time, to change events sufficiently to make absolute certain this nightmare future never get a chance to happen in the first place!"
