The third season of the Sunday Author Talks starts Sunday at 4 p.m. when Pulitzer Prize winning journalist Philip Caputo talks about his new book, “The Longest Road,” at the Paul Pratt Memorial Library.

Admission is free, but seating is limited. The series continues monthly through April, and upcoming authors include fiction writer Andre Dubus III, Jay Parini, physicist John Huth, biographer Megan Marshall, historian Jeffrey Bolster, and Barbara Shapiro.
