Plot summary
Centaurus is the destination of the space ship The Hope of Man. It has been traveling through space for almost twenty years, and still has nine years of flight remaining. For many on board the craft, Earth has become a vague memory, while for others it is a mere dot in the vast starry reaches of space. Restlessness is evident everywhere; the people want to return to a place they know is inhabited - not continue to an unknown where life is uncertain. Mutiny seems inevitable. Captain Lesbee (the ship's main officer) knows that mutiny breeds mutiny, but what is more significant is his knowledge of Earth's possible obliteration. The one hope is Centaurus. Now more than ever, there can be no turning back. Order has to be maintained even at the price of human life.

After reaching Centaurus and finding it unsuitable for human life, The Hope of Man heads towards the next destination, the Alta system. Because the ship is unable to attain light speed it takes decades to travel there. Upon arriving in the system, after mutiny and treachery, The Hope of Man is now captained by Browne, a descendant of the ship's original First Officer. The Hope of Man enters into orbit around Alta III, but find it already inhabited and come under attack from the occupants. During this time we see a struggle for power by various groups. Control changes quickly from one character to another until the arrival of the ship's owner, Averill Hewitt. The novel concludes with Hewitt in charge and the ship finding many planets to inhabit.
