The Book Festival of the Marcus Jewish Community Center concluded another epic season Sunday night, Nov. 22, with Ted Koppel talking about “Lights Out,” his warning about the vulnerability of the U.S. electric grid and the catastrophic consequences if an enemy leaves us in the dark through a cyberattack. The final weekend also included legendary lawyer Alan Dershowitz with his book on the first Jewish lawyer, “Abraham”; Atlantans Josh Levs (“All In”) and Joey Reiman (“Thumbs Up!”); and spiritual writer Laurie Ann Levin (“Life in Life”).
