EVAN THOMAS appears at the Atlanta History Center for a discussion and signing of his book The War Lovers. While we could never relate to this today, there was a time when America rushed into foreign affairs, media moguls were driven by the mighty dollar, and the government lusted for war. Wait ... well, see how it all began as Thomas investigates the 1898 explosion of the USS Maine and the political heavy hitters who waged war and imperialism. $5-$10, reservations required. 8 p.m. 130 W. Paces Ferry Road. 404-814-4000. www.atlantahistorycenter.com.
