A huge success in England, this marvelously funny debut novel had its genesis in a column Fielding writes for a London newspaper. It's the purported diary, complete with daily entries of calories consumed, cigarettes smoked, ""alcohol units"" imbibed and other unsuitable obsessions, of a year in the life of a bright London 30-something who deplores male ""fuckwittage"" while pining for a steady boyfriend. As dogged at making resolutions for self-improvement as she is irrepressibly irreverent, Bridget also would like to have someone to show the folks back home and their friends, who make ""tick-tock"" noises at her to evoke the motion of the biological clock. Bridget is knowing, obviously attractive but never too convinced of the fact, and prone ever to fear the worst. In the case of her mother, who becomes involved with a shady Portuguese real estate operator and is about to be arrested for fraud, she's probably quite right. In the case of her boss, Daniel, who sends sexy e-mail messages but really plans to marry someone else, she's a tad blind. And in the case of glamorous lawyer Mark Darcy, whom her parents want her to marry, she turns out to be way off the mark. (""It struck me as pretty ridiculous to be called Mr. Darcy and to stand on your own looking snooty at a party. It's like being called Heathcliff and insisting on spending the entire evening in the garden, shouting `Cathy!' and banging your head against a tree."") It's hard to say how the English frame of reference will travel. But, since Bridget reads Susan Faludi and thinks of Goldie Hawn and Susan Sarandon as role models, it just might. In any case, it's hard to imagine a funnier book appearing anywhere this year. Major ad/promo; first serial to Vogue; BOMC and QPB main selections; simultaneous Random House audio; author tour.
