The coming-of-age story is a summer book standard. So many of us remember spending our lazy summer days with Francie from “A Tree Grows in Brooklyn,” the March sisters of “Little Women” or Holden Caulfield of “Catcher in the Rye.” The next pick for our Summer Book Club furthers this tradition through a uniquely accurate adolescent voice. Jo Ann Beard’s “In Zanesville” follows a teenage narrator and her best friend through high school life in 1970s small-town Illinois. The novel is so transfixing, Celeste claimed she couldn’t put it down. John finished it and immediately passed it along to his daughters. Author Jo Ann Beard joins us in the studio.
