George Saunders has seen the future of America and it is funny. Bleak, yes, and sad and toxic and greedy - and very, very weird - but funny, too. With today's malls and theme parks and ecological disasters as their foundation, these stories build a tomorrow inhabited by fat executives in despair, genetic mutants in servitude, virtual-reality merchants in Chapter 11, and American Dreamers everywhere in trouble.

A lot of this book's business is business in an America whose culture and economy are falling apart, business on the fringes, business on the skids. The marginal entrepreneurs who people its pages hawk everything from glimpses of a living see-through cow to raccoon meat to old ladies' memories. Deregulation rules and brigands thrive.

But at the center of George Saunders's fiction stand those hapless souls who suffer most keenly. the injustices and inequalities that a Free Market dishes out - the guys who just can't make it or run into plain old bad luck. A self-abasing minion at CivilWarLand suggests a way to rid the premises of the teenage gangs that prowl the grounds at night, only to find the cure far more dangerous than the disease. Another poor sap, who runs a wavemaking machine, allows himself a moment of underling's vanity and accidentally kills a kid frolicking in the artificial surf.

And in the picaresque novella "Bounty," a futuristic descendant of Huckleberry Finn with claws for feet travels across the ramshackle country to rescue his sister, also a mutant, who has been bought by a Normal for pleasure and, possibly, profit.

These astute stories recall not only the work of Mark Twain but also such diverse figures as Jonathan Swift and Kurt Vonnegut. At once cautionary and, in their humor, entertaining and redemptive, they help us see our society and ourselves in new and startling ways.
