In Porter's second dip into the chick lit pool (after The Frog Prince
), Seattle single mom Jackie Laurens begins wondering how important happiness is: divorced with two kids and a thriving decorating business, she assumes she's happy, but can't help feeling like something's missing. When her married friend, Anne, arranges for the two of them to indulge in a Hawaiian getaway in honor of Jackie's 40th birthday, Jackie agrees. Anne backs out at the last second, but Jackie decides to suffer through the vacation solo. Hawaii is gorgeous, but the hotel pool deck groans under the weight of middle-aged men whose coarse chutzpah is only overshadowed by their flabby bellies. Just before she resigns herself to the depressing prospects, she meets Kai, a sexy, tan and much younger surfing instructor. Life doesn't get better, only more complicated as Jackie tries to balance the sultry, sweaty joys of Hawaii and Kai with the obligations of motherhood. Porter's romance roots show in the gratuitous sex scenes and in how easily tears flow from Jackie's eyes, but this book fits the bill as a calorie-free accompaniment for a poolside daiquiri. (July)
