The Quiet War is over. The city states of the moons of Jupiter and Saturn, founded by descendants of refugees from Earth’s repressive regimes, the Outers, have fallen to the Three Powers Alliance of Greater Brazil, the European Union, and the Pacific Community. A century of enlightenment, rational utopianism and exploration of new ways of being human has fallen dark. Outers are herded into prison camps and forced to collaborate in the systematic plundering of their great archives of scientific and technical knowledge, while Earth’s forces loot their cities and settlements and ships, and plan a final solution to the ‘Outer problem.’ But Earth’s victory is fragile, and riven by vicious internal politics. While seeking out and trying to anatomise the strange gardens abandoned in place by the Outers’ greatest genius, Avernus, the gene wizard Sri Hong-Owen is embroiled in the plots and counterplots of the family that employs her.
