YOU KNOW YOU LOVE ME. A Gossip Girl Novel. (C.vo

College interviews, romantic troubles and a fancy wedding photographed for Vogue dominate this second installment of von Ziegesar's frothy but fun series about rich Manhattan prep school kids and the gossip Web site tracking their lives. Blair Waldorf's mother is marrying her seriously tacky boyfriend on Blair's birthday and has chosen the bulimic overachiever's former best friend Serena as a bridesmaid (Blair will be maid of honor). Meanwhile, hunky Nate avoids Blair (he's secretly seeing chesty Jenny Humphrey), and the compounded stress makes her act like a freakshow during her Yale interview. Blonde bombshell Serena is disturbed by poet Dan's intense affections, struggles through her own interview at Brown and scores first prize in a school film contest. The plot culminates at the wedding, where the girls' boy troubles come to a head. As with her Gossip Girl, von Ziegesar creates a complete world: the characters get drunk, shop and indulge in spa treatments plus, the film contest prize is two tickets to Cannes. While this is still strictly a guilty pleasure, the story lines are better developed in this volume and the characters show more growth. But it's their outrageous lifestyles and antics and the snide omniscient narrator that will keep readers turning the pages. Ages 15-up.
