Norris Church Mailer, who is married to Norman Mailer, made her fictional debut three years ago with a coming-of-age story called Windchill Summer, and now Random editor Lee Boudreaux has signed the former model for a new book on a world she knows well—high fashion. It's called Cheap Diamonds and is about the fast lane in the Manhattan modeling world. The North American rights deal was for six figures with bonuses, made with John Taylor Williams at Boston's Kneerim & Williams.
