This book takes the case of the civil war disappeared in Lebanon to draw on fiction’s potential to inform peacebuilding processes by allowing the exploration of invisible histories in postwar Beirut. In its close reading of three Lebanese novels by Rabee Jaber, the book follows a multidisciplinary approach that puts trauma theory in dialogue with the Lebanese context and Arabic language, producing new concepts, models, and questions related to trauma, loss, and history, while also reflecting on the role fiction, as a cultural production, can play.
