HarperCollins Book Deal for Jenna Bush (Radar)
It's hard out there for would-be first-time authors — unless your dad is the president, y'all! First daughter Jenna Bush has landed the book deal she was fishing for, with HarperCollins announcing plans to publish Ana's Story: A Journey of Hope this fall.
