NOW THAT Zero History (Berkley; August 2), by “cyberspace” coiner and Vancouver, BC, inhabitant William Gibson, is in paperback, we can devour the high-tech thriller as it was meant to be devoured: at the beach—at a gray-skies-and-even-grayer-seas Northwest beach. In this sequel to Spook Country, drug addict Milgrim and erstwhile rocker Hollis Henry uncover the secret connection between fashion and military apparel—using iPhones, Twitter, and every other imaginable technology of the moment. Choice line for coffee shop dwellers: “The cost of wifi was white pear tea.”
