"A billion husbands are about to be replaced." From the author of Fight Club, the classic portrait of the damaged contemporary male psyche, now comes this novel about the apocalyptic marketing possibilities of a new product that gives new meaning to the term "self-help."  Penny Harrigan is a low-level associate in a big Manhattan law firm with an apartment in Queens and no love life at all. So it comes as a great shock when she finds herself invited to dinner by one C. Linus Maxwell, a software mega-billionaire and lover of the most gorgeous and accomplished women on earth. After dining at Manhattan's most exclusive restaurant, he whisks Penny off to a hotel suite in Paris, where he proceeds, notebook in hand, to bring her to previously undreamed-of heights of gratification for days on end. What's not to like? This: Penny discovers that she is a test subject for the final development of a line of feminine products to be marketed in a nationwide chain of boutiques called Beautiful You. So potent and effective are these devices that women by the millions line up outside the stores on opening day and then lock themselves in their room with them and stop coming out. Except for batteries. Maxwell's plan for battery-powered world domination must be stopped. But how?
