Steve Rubin and Maria Campbell threw a party last night for former HarperCollins ceo Jane Friedman on the roof Rubin’s apartment building, attended by longtime publishing colleagues and, apparently, a few publishing reporters. The guests surprised Friedman by wearing printed Jane Friedman masks. She called it her “transition party” and noted: “What I’m going to say –and this is it– is I am not done, and I am not done by a long shot.” But there’s no report on what she is transitioning to yet.Observer
