+Our protagonists are Sherkaner Underhill (mad scientist extraordinaire), Gen. Victory Smith (an oophase military prodigy, and Underhill's wife), and Sgt. Hrunkner Unnberby (an engineer, and Underhill and Smith's friend and comrade from the Great War). After the war, Underhill and Smith deliberately conceive children out of phase. Underhill is motivated by a zeal for progress: a champion of plans to use the new discovery of atomic power to keep civilization running while the sun is off, he reasons that the anti-oophase taboo will be unnecessary in the new world they're building. Smith seems motivated to pass on her oophase legacy to her children, and give them a more supportive environment than the one she faced.
