Sadie by Courtney Summers is a haunting and emotionally powerful novel that blends thriller, mystery, and social commentary. Told through alternating perspectives—a serialized podcast and Sadie’s own journey—the story follows a teenage girl who sets out to find the man who murdered her younger sister, but disappears in the process. The podcast host tries to piece together what happened to her, uncovering painful truths along the way. In this course, students will explore the novel’s dual narrative structure and how it builds suspense and deepens the emotional impact. We will examine themes such as trauma, vengeance, justice, and the vulnerability of marginalized voices. The class will also discuss the role of media in storytelling and truth-seeking, and how Sadie’s voice offers a powerful critique of societal neglect.
