Last spring, Sophie Kinsella's hardcover debut, Can You Keep a Secret?, became her first hardcover national bestseller, and this week, the trade paperback reprint lands in the #11 spot after alittle more than a week on sale. The novel has more than 250,000 copies in print after two trips to press. For the paperback publication, Delta partnered with ElleGirl magazine and its Web site to give away copies, with one lucky winner getting a "secret" shopping trip to New York City. Fans have only to wait until July for Kinsella's next novel, The Undomestic Goddess, published as a Dial Press hardcover. (See Hollywood Reader for more.)
