THE SISTERHOOD OF THE TRAVELING PANTS

First novelist Brashares successfully creates four distinct characters, each with her own story line, and ties them together with a creative device: a pair of pants purchased in a thrift shop. As four lifelong friends prepare to split up for the summer, they discover that the second-hand jeans look good on all of them, despite their different physiques. They promise to rotate the jeans among them and, upon their reunion at summer's end, record their favorite adventures on the pant legs. These magical pants serve as a substitute friend for each girl as she is tested that summer, from Carmen, who goes to visit her father only to find out he's engaged to a woman with two teenage kids, to Tibby, who befriends a precocious 12-year-old cancer victim. Even though they are separated for most of the summer, the friends communicate their love and understanding for one another (Tibby writes to Lena, "Don't torture yourself, Len. We love you too much," to console her friend for mistakenly accusing a cute neighbor boy of spying on her while she skinny dips in Greece). Their bonds, combined with a realistic portrayal of teen emotions (Tibby is embarrassed by the smock she has to wear to work at Wallman's, while Carmen boils with rage when the seamstress fitting her bridesmaid dress disparages her curvy figure), make for an outstanding and vivid book that will stay with readers for a long time. Readers will hope that Brashares chronicles the sisterhood for volumes to come. Ages 12-up. (Sept).
