Seed of Light

Description:

"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 children. For the ship was a self-contained world, required to support human life independently for centuries. This is the story of these men and women, and the incredible generations who followed them"
