In 2034, the stars went out. An unknown agency surrounded the solar system with an impenetrable barrier, concealing the universe from humanity’s gaze. In 2067, Nick Stavrianos is hired to investigate the disappearance of a mentally disabled woman, Laura Andrews, from the institution where she was being cared for. Aided by a skull full of neural modifications, he follows her trail to the Republic of New Hong Kong, where an organisation known as the Ensemble has uncovered Laura’s extraordinary secret: an ability that could transform the world.

From back cover HarperPrism paperback November 1999: It is the thirtieth century. The "world" has evolved into a vast network of probes, satellites, and servers knitting the solar system into one scape from the outer planets to the sun. Humanity, too, has reconfigured itself. Most people have chosen immortality, joining the polises to become conscious software. Others have opted for disposable, renewable robotic bodies that remain in contact with the physical world. A few holdouts stubbornly remain fleshers struggling to shape an antiquated existence in the muck and jungle of Earth. And then there is the Orphan, a genderless digital being grown from a mind seed. WHen an unforeseen disaster ravages the fleshers, it awakens the polises to the possibility of their own extinction from bizarre astrophysical processes that seemingly violate fundamental laws of nature. It is up to the Orphan and a group of refugees to find the knowledge that will save them all -- a search that will lead them on a quantum adventure to a higher dimension beyond the macrocosmos....

"In an alien universe, the generation ship Peerless has set out to save its home world from annihilation. But the Peerless is facing urgent problems of its own. It does not carry fuel to return home, so without a new form of propulsion it will remain stranded in space. A population explosion has stretched life support to its limits, and the biology of the travellers offers only one way to prevent growth: subjecting the women to famine to limit the number of children they bear. When the astronomer Tamara discovers the Object - a massive meteor just within reach - hopes rise that there might finally be a solution to the fuel crisis. As an expedition is organised, a biologist struggles to devise a better way to control fertility, while his partner stumbles on a strange phenomenon that challenges everything she thought she knew. As the three scientists clash with the prejudices of their society, they find themselves swept up in two dangerous revolutions: one in their understanding of matter and energy, the other in the roles imposed by their species on women and men. Either change may destroy the ship - together, they might save their world."

Camille is desperate to escape her home on colonized asteroid Vesta, journeying through space in a small cocoon pod covertly and precariously attached to a cargo ship. Anna is a newly appointed port director on asteroid Ceres, intrigued by the causes that have led so-called riders like Camille to show up at her post in search of asylum. Conditions on Vesta are quickly deteriorating - for one group of people in particular. The original founders agreed to split profits equally, but the Sivadier syndicate contributed intellectual property rather than more valued tangible goods. Now the rest of the populace wants payback. As Camille travels closer to Ceres, it seems ever more likely that Vesta will demand the other asteroid stop harboring its fugitives. - inside front cover.

Far in the distant, post-human future, the Cater-Zimmermann community set out to refute the theory that the universe is created exclusively for mankind by cloning themselves a thousand times over and sending each copy to a different star within the galaxy. One of the copies of Cater-Zimmermann, Paolo Venetti, arrives at Orpheus; a water-world inhabited by floating mats that perform as a Turing machine.

"Twenty stories and novellas, each of them a brilliantly conceived, painstakingly developed gem, including the Hugo-winning novella Oceanic. This is an important and provocative collection, and it deserves a place on the serious science fiction reader's permanent shelf."
