Planet Jijo is forbidden to settlers, its ecosystem protected by guardians of the Five Galaxies. Yet, over centuries, refugees of six intelligent races have come, weaving 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 lands on Jijo. Does it bring the long-dreaded judgment, or worse - criminals bent on destroying the six races of Jijo in order to cover their own crimes? Can the exiles unite and find a way to save themselves . . . and a galaxy beyond?
