This weekend, literary folks across the metro area will have an awesome chance to catch sight of celebrity authors. The third annual Decatur Book Festival will kick off on Friday night with a keynote speech by Billy Collins, a former United States poet laureate; tickets are required for this event, but are available free at Agnes Scott College’s box office and several local bookstores. There will be 250 national and local authors speaking around Decatur. These authors include Pearl Cleage, Eric Jerome Dickey, Emily Giffin, Kathy Reichs, Karin Slaughter and Haywood Smith. If you have children, fear not! This is a completely family friendly event. There will be a children’s parade Saturday morning with beloved costumed characters and a marching band. There will be many authors for children and teens reading from and speaking about their work, including John Bemelmans Marciano (the grandson of the author of Madeline), Chris Raschka, and Doreen Cronin.
