Surfing across the transfinite dimensions, this giddy sequel to 2007’s Postsingular
chronicles the fight to keep Earth “gnarly” in the face of aliens who want to steal the quantum chaos that makes the planet interesting. Metanovelist Thuy and her husband, JayJay, who’s addicted to the global groupmind called Gaia, maneuver between worlds to fend off chaos-diverting Peng real estate developers and flying manta-ray Hrull. Math prodigy Chu, who mitigates his autism with telepathy, and a parallel universe Hieronymus Bosch join Thuy and JayJay as they escape from modern-day fundamentalists and Renaissance witch-hunters and try to keep Gaia from going volcanic. Rucker’s plotting can be as loopy as his time lines, and the ending is so confusing that even his characters complain, but his wild imagination never slows down. (June)
