It is the distant future. The world known as Virga is a fullerene balloon three thousand kilometers in diameter, filled with air, water, and floating chunks of rock. The humans who live in this vast environment must build their own fusion suns and "towns" enormous wood and rope wheels that are spun for centripetal gravity.

This complex and fascinating world is the setting for the novels of Virga, Karl Schroeder's interstellar far-future space habitat sealed off from contamination by the rest of the inhabited universe. These books have set a high standard for hard SF adventure in the last...

Return to Virga, a bubble universe artificially separated from our own future universe, and the setting ofSun of Suns and Queen of Candesce.

Chaison Fanning, the admiral of a fleet of warships, has been captured and imprisoned by his enemies, but is suddenly rescued and set free. He flees through the sky to his home city to confront the ruler who betrayed him. And perhaps even to regain his lovely, powerful, and subversive wife, Venera, who he has not seen since she fled with the key to the artificial sun at the center of Virga, Candesce.

With Pirate Sun,...
