At a New York City jet-set private school populated by hard-drinking, bulimic, love-starved poor little rich kids, a clique of horrible people behave badly to one another. An omniscient narrator sees inside the shallow hearts of popular Blair Waldorf, her stoned hottie of a boyfriend, Nate, and her former best friend Serena van der Woodsen, just expelled from boarding school and "gifted with the kind of coolness that you can't acquire by buying the right handbag or the right pair of jeans. She was the girl every boy wants and every girl wants to be." Everyone wears a lot of designer clothes and drinks a lot of expensive booze. Serena flirts with Nate and can't understand why Blair is upset with her; Blair throws a big party and doesn't invite Serena; Serena meets a cute but unpopular guy; and a few less socially blessed characters wonder about the lives of those who "have everything anyone could possibly wish for and who take it all completely for granted." Intercut with these exploits are excerpts from www.gossipgirl.net (the actual site launches in February), where "gossip girl" dishes the dirt on the various characters without ever revealing her own identity amongst them. Though anyone hoping for character depth or emotional truth should look elsewhere, readers who have always wished Danielle Steel and Judith Krantz would write about teenagers are in for a superficial, nasty, guilty pleasure. The book has the effect of gossip itself once you enter it's hard to extract yourself; teens will devour this whole. The open-ended conclusion promises a follow-up. Ages 15-up.
