The planet Jijo is forbidden to settlers, its ecology protected by guardians of the Five Galaxies. But over the centuries it has been resettled, populated by refugees of six intelligent races. Together they have woven a new society in the wilderness, drawn together by their fear of Judgment Day, when the Five Galaxies will discover their illegal colony. Then a strange starship arrives on Jijo. Does it bring the long-dreaded judgment, or worse--a band of criminals willing to destroy the six races of Jijo in order to cover their own crimes?
From the Paperback edition.
Millennia ago the Five Galaxies decreed the planet Jijo off limits. But in the last thousand years six races have begun resettling Jijo, embracing a pre-industrial life to hide their existence from the Galactics. Overcoming their differences, the Six have built a society based on mutual tolerance for one another and respect for the planet they live on. But that has all changed with an event the Six have feared for hundreds of years: the arrival of an outside ship. Author David Brin has returned to his popular Uplift universe in this, the first book of a new trilogy.
