Alt-cultural folk strive to save Earth from digitized doom in this novel from the prince of gonzo SF. A computer mogul’s threat to replace messy reality with clean virtuality and by a memory-hungry artificial intelligence called the Big Pig propels nanotechnologist Ond Lutter, his autistic son, Chu, and their allies on an interdimensional quest for a golden harp, the Lost Chord, strung with hypertubes that can unroll the eighth dimension and unleash limitless computing power. Though he tries to unite the hard and the fuzzy sides of physics, Rucker (Mathematicians in Love ) favors the flower power of San Francisco over the number crunching of Silicon Valley. His novel vibrates with the warm rhythms of dream and imagination, not the cold logic of programming (or, for that matter, plotting). Playing with the math of quantum computing, encryption and virtual reality, Rucker places his faith in people who find true reality “gnarly” enough to love. (Oct.)
