In this outstanding sequel to Wilson's Hugo-winning Spin (2005), we are taken to the mysterious planet Equatoria, a world apparently engineered for humanity by the inscrutable machine intelligences known as the Hypotheticals. Turk Findley, a man with a criminal past, runs an aeronautical charter service on the newly settled planet. Lise Adams, who hires Turk, is a would-be journalist searching for her vanished father, a scientist obsessed with the Hypotheticals and their illegal life extension technology. Meanwhile, young Isaac, genetically manipulated by rogue scientists so that he may become a conduit between humanity and the AIs, is coming of age, and something enormous and unknown is assembling itself far underground. The various science and thriller plot elements are successful, but this is first and foremost a novel of character. Turk and Lise, who might well be played by Bogart and Bacall, are powerfully drawn protagonists, and their strong presence in the novel makes the wonders provided all the more satisfying. Those unfamiliar with Spin may flounder a bit, but Wilson's fans will be ecstatic. (Sept.) «
