When East End cabdriver Dave Rudman's wife takes from him his only son, Dave pens a gripping text--a compilation about everything from the environment, Arabs, and American tourists to sex, Prozac, and cabby lore--that captures all of his frustrations and anxieties about his contemporary world. Dave buries the book in his ex-wife's Hampstead backyard, intending it for his son, Carl, when he comes of age.  Five hundred years later, Dave's book is found by the inhabitants of Ham, a primitive archipelago in post-apocalyptic London, where it becomes a sacred text of biblical proportions and the template for a new civilization. Only one islander, Symum, remains incredulous. But, after he is imprisoned for heresy, his son Carl must journey through the Forbidden Zone and into the terrifying heart of New London to find the only thing that will reveal the truth once and for all: a second Book of Dave that repudiates the first.  The Book of Dave is a profound meditation upon the nature of religion and a caustic satire of contemporary life.
