Peter Tupper has written a great feature on my books for the Vancouver Sun, with a special emphasis on Eastern Standard Tribe (there's also a review of EST, but you have to buy a daily subscription to the print paper to read it -- lame!).
While some might consider Doctorow a booster for the online, wired lifestyle, his books contain subtle but pointed warnings about the flaws of high tech societies. Being a Tribalist, living out of circadian synch with the people around you, relating with people you mainly know as a handle on a screen, encourages paranoia and disloyalty, smartness instead of happiness. Art becomes an object lesson in how such a society can ruin a person, and his salvation doesn’t lie in technology.
