Nora Roberts lands more titles on the national charts than any other author, and her 2003 count was stronger than ever. During 2003, she had 15 books on the mass market bestseller lists (she has three on the current list), for a total of 70 weeks; that accounts for an almost 10% share. She also had three trade paper and two hardcover bestsellers. Her Jove/Berkley 2003 mass market titles (Portrait in Death, Three Fates, Imitation of Death, Key of Light, Key of Knowledge) and two Berkley 2003 hardcovers (Birthright and Remember When) have a combined total of nearly 12 million copies in print. Harlequin reports close to 10 million copies in print for its 2003 Roberts bestsellers (Truly Madly Manhattan, Engaging the Enemy, Mysterious, Sullivan's Woman, Love by Design, Less of a Stranger, Temptation and Lawless). Both the author and her fans had a busy 2003.
