Washington University in St. Louis ran a First-Year Reading Program contest for students to create their own chapter to the novel The Cellist of Sarajevo by Steven Galloway. Juliet Kinder, the Grand prize winner tells the story from the point of view of Arrow, a gifted female sniper who protects the cellist from a hidden shooter as he plays a memorial to the twenty-two people killed in his neighborhood waiting in a bread line.
