The pristine city of Elysium floats on the water world of Shora, inhabited by "immortals" who have succeeded in unlocking the secrets of life. Outsider Blackbear Windclan wants to share the secret of immortality with his own people, but can he, and the City of Elysium, survive the corruption and decadence that immortality has bred into the ageless society?

And what of the consciousness of self-aware nano-sentient servitors and their quest for vengeance?

***Like its predecessor, A Door into Ocean , this thoughtful, well-crafted novel is set on the ocean world of Shora. Shora's original settlers, the Sharers, are peace-loving women who live in close harmony with nature. They now share their world with the 12 floating cities of Elysium, a society of nearly ageless humans who live surrounded by wealth and advanced technology. (Publishers Weekly)***
