The Casualty of Regret explores the lasting consequences of a school shooting through the lives of those left in its shadow: grieving parents, a witness teacher, and a journalist searching for truth. As hidden pasts and buried secrets surface, the story reveals the complex web of guilt, responsibility, and regret that extends far beyond the crime itself. Told through multiple perspectives, this psychological thriller examines how a single tragic event fractures lives, and how the search for understanding can expose truths no one is prepared to face.
