Fall is the time for “big books,” whatever the page length, and some of the top fiction authors from around the world have new works coming, including Ian McEwan, Zadie Smith, Margaret Atwood, T. Coraghessan Boyle, Rabih Alameddine, Emma Donoghue, Jonathan Safran Foer and Michael Chabon. Ann Patchett, owner of Parnassus Books in Nashville, Tennessee, looks forward to selling Jacqueline Woodson’s autobiographical novel “Another Brooklyn” and Colson Whitehead’s celebrated, Oprah Winfrey-endorsed historical novel about slavery, “The Underground Railroad.”
