Six years after the first anonymous blogpost rocked New York society, Season Six opens with the Upper East Siders working together to find Serena, who's gone off the grid. Blair and Chuck reunite with a bang, but can her love help him win back his empire? Lonely Boy Dan writes a new tell-all book that's even more revealing than the first, Nate plans to put The Spectator on the map by exposing Gossip Girl's identity, and Rufus's surprising new ally threatens Lily and her family. This much drama would be too hot to handle for mere mortals, but when these socialites decide to raise hell, it's a fight to the spectacular series finale!
