Each year, more than eight million people in the United States are diagnosed with Post-Traumatic Stress Disorder (PTSD). This disorder is a true silent killer, and local author Kaitlyn Gant is shattering the silence and telling the world about surviving the disorder in her book entitled “Will You Listen?” Gant will be holding a benefit book signing event on Thursday, May 5 from 10 a.m. to 12 p.m. at the Village Coffee Roastery in Scottsdale.
