Ally Condie, author of one of the hottest teen book series since the “Twilight” and “The Hunger Games” sagas, will speak and sign copies of her books at 7 p.m. Wednesday, Oct. 3, at Brenau University’s Pearce Auditorium. The event is free and open to the public. Condie’s dystopian saga “Matched” became an international best-seller when it was published in 2010.
