Serialized in Galaxy (December, 1961 & February, 1962) as "The Day After Doomsday". First book edition in 1962.
Carl Donnan was a space enginer – a man of action who did his job well and didn't think much beyond that – but now his home planet was destroyed and he found himself with two burning ambitions:
Find the beings who blew up the Earth.
Search the galaxies until they located another Starship with female humans aboard.
Both projects were vital to the survival of the human race – and both were monumental tasks.
This was the time when the galaxies discovered how grim and purposeful a handful of homo sapiens could be.
