A sequel to The Time Machine by H. G. Wells.
The Time Traveller, named George, and the pregnant Weena try to return to his time, but instead land in the London Blitz, dying during a bombing raid. Their newborn son is rescued by an American ambulance driver, and grows up in the United States under the name Christopher Jones. Sought out by the lookalike son of James Filby, Jones goes to England to collect his inheritance, leading ultimately to George's journals, and the Time Machine's original plans. He builds his own machine with 1970s upgrades, and seeks his parents in the future.
