Seed of Light — Edmund Cooper

TEN MEN AND WOMEN ESCAPED IN THE STARSHIP - THE ONLY HOME THEY WOUKD KNOW FOR GENERATIONS - THE SEED FROM WHICH THEY WOULD BUILD A NEW RACE.

The Solarian was a hundred metres high and, at its broadest point, twenty metres in diameter. It was designed to carry an initial crew of ten people - five men and five women - with provisions for subsequent children. Yet in that vast hull every cubic metre of space was indispensable, for the ship was a self-contained world, required to support human life independently for centuries.

No member of the crew, male or female, could regard themselves as a separate entity, an individual personality. But each person was a part of a total life-unit, a dedicated nucleus that might one day expand into a tribe; that might, phoenixlike, bring forth a new human race.
