In "Mill Daddy, " Bill Lightle has given us both an enduring love story and a tribute to Roy Davis' indomitable spirit that sustained him and his poor family through sharecropping, the suffering of the Great Depression, and the hard, hard life in a Georgia cotton mill. As Lightle writes, Roy Davis "was an authentic American hero." The book also details the often hilarious adventure that Lightle and some of his teenage friends had working under Roy Davis in the Flint River Cotton Mill in the 1970s.
