Before ripped Louis Vuitton clutches and earsplitting fights were depicted on every television screen, the stars of reality TV had lives, too. NENE LEAKES from “The Real Housewives of Atlanta” has written a memoir of what her days were like before the TV life. Never Make the Same Mistake Twice tells a story even more eventful than her Bravo docudrama, including childhood struggles, violent abuse from a boyfriend and the challenges of supporting her first son — not to mention more up-to-date items such as clearing rumors and dishing on her co-stars. Leakes signs books today right here in home-sweet-home Georgia. Free. 7 p.m. Barnes & Noble, 2900 Peachtree Road, N.E., Suite 310. 404-261-7747. barnesandnoble.com.
