Bow down, Blair Waldorf is officially returning to the Upper East Side. A new standalone novel titled ‘Blair’, written by original Gossip Girl author Cecily von Ziegesar, is in the works, and Deadline confirms it’s already landed in a major publishing deal.Set 20 years after the original series, the novel follows Blair in her 40s - older, sharper, and still very much in control. We’re talking power, privilege, ambition, and the kind of social maneuvering only Blair Waldorf could master. Manhattan may have changed, but make no mistake she hasn’t lost her edge.
