It is our national novel. Reading to Kill a Mockingbird is something we all have in common. Harper Lee’s first and only novel turns 50 this summer and the author hasn’t given an interview since 1964 or published a second book. In compelling interviews with Scott Turow, James McBride, Wally Lamb, Rosanne Cash, Anna Quindlen, Oprah Winfrey,Tom Brokaw, among others, and with rare cooperation from Harper Lee’s sister and friends, Mary Murphy traces the history of this astonishing phenomenon.
