Going by the numbers, James Patterson and Maxine Paetro lead the build-up to Memorial Day, with an announced 1.25 million printing, followed by David Baldacci, with half that. The Reagan Diaries and Pope Benedict top the nonfiction list, with upward of 200,000 copies each, while literary kingpins Michael Chabon and Don DeLillo weigh in around that range. In children's books, John Grogan trots out two more tributes to his dog, Marley, to the tune of more than 600,000 copies.
