Katia D. Ulysse presents Mouths Don’t Speak at the Brooklyn Book Festival. Location: Brooklyn Borough Hall Courtroom, 209 Joralemon Street.

THE AFTERMATH: Psychological, unseen injuries are often the most difficult to identify and treat. As medicine struggles to diagnose and treat post-traumatic stress disorder, literature is recognizing its reality and import. Novelists Shahriar Mandanipour (Moon Brow), Katia D. Ulysse (Mouths Don’t Speak), Dan Sheehan (Restless Souls) join Sara Nović (Girl at War) to explore the power of PTSD, whether it’s acquired on the battlefield or on the home front.
