Thousands of years in the future in a distant part of the galaxy, lies the planet Shora, entirely covered by a world-spanning ocean. The huge and complex ecosystem of Shora is inhabited by the Sharers, an all female race who reproduce by parthenogensis, without males. The Sharers are immensely sophisticated in the life sciences, but have eschewed all unnatural technology. Over millennia of isolation, they have developed a complex philosophical and ethical system, idealistic, communal, and pacifist...

So begins a war, protracted and graphic, in which one side cannot fight because the concept is inconceivable in their philosophy...

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 vengence?

Only children can colonize the planet Prokaryon, genetically modified for a world whose chemistry kills unaltered adults. A colony of orphans struggle to survive, and find the planet hides strange secrets. ***** The Prokaryan landscape is ordered, as if by unseen gardeners, "hidden masters" no human has ever found. The weather behaves as though designed to meet the planet's needs. When fire threatens a forest, a rainstorm appears, only to dissipate when the fire is put out. ***** When a ruthless corporation threatens to terraform Prokaryon, to recreate it for "normal" humans, there is a sudden urgency to find the intelligent life form directing the planet. For only then can the colonists save their world-and reveal unexpected possibilities for the human future.

In Joan Slonczewski's Brain Plague...a starving artist on the planet Veledon agrees to let a colony of "brain enhancers" occupy her skull. These microscopic creatures live in the brain's outer linings, causing bursts of genius-or irreparable harm. The creatures themselves are like tiny human beings; one of their greatest concerns is getting their young to breed.
