Book excerpt: Thirtysomething best friends Kit and Bridget flee their humdrum lives to spend the summer in Positano, the infamous "Pearl of the Amalfi," for a once-in-a-lifetime vacation filled with frivolously expensive and tantalizingly wonderful experiences-and that was just the food. Kit is in love with the cliff side resort town -and with Lassino, a pizza chef who lives there. At the prospect of spending the summer in a country synonymous with pizza and gelato, neurotically obsessive and weight-conscious Bridget is already in panic mode. But she's ready to risk a few pounds to get away from it all for a few months. So she and Kit rent an apartment, and they invite their friends over for a visit. They find themselves with no shortage of good friends who want to spend time in Italy on the cheap. Their idyllic summer getaway flies by, thanks to a wedding, a death threat, a missing teen, a lunatic Australian, love on the rocks, a pregnancy, and lots and lots of sparkly prosecco.
