Welcome to New York City's Upper East Side, where my friends and I live, go to school, play, and sleep-sometimes with each other. It's a luxe life, but someone's got to live it . . . until they die. So begins Gossip Girl, Psycho Killer , a re-imagined and expanded slasher edition of the first groundbreaking Gossip Girl novel, featuring all new grisly scenes and over-the-top gore by #1 New York Times bestselling author Cecily von Ziegesar. Just as in the original story, Serena returns from boarding school hoping to make amends with her BFF Blair Waldorf--things just haven't been the same since Nate Archibald came between them. But here's where our dark tale takes a turn: Serena decides that the only way for her to make things right with Blair is to eliminate Nate. If that means killing him, well, c'est la vie . Her attempted murder doesn't go unnoticed by Blair, however, who isn't about to let Serena kill whoever she wants-not when there's Cyrus Rose and Chuck Bass and Titi Coates and everyone else who's ever irritated Blair to get rid of first . . . . American Psycho 's Patrick Bateman has met his match in Manhattan's newest, most fabulous trendsetting serial killers, Blair Waldorf and Serena van der Woodsen.
