Centered on a young girl who inexplicably stops speaking, December is a riveting and insightful portrait of a family in crisis. Nine months after eleven-year-old Isabelle suddenly fell silent, her parents, Wilson and Ruth, are at their wits' end. And what began as self-protection has spiraled beyond Isabelle's control; she has become trapped in her silence, horrified by the pain she is causing and terrified of losing her old self to this cold young girl she barely recognizes. Isabelle must confront her overwhelming anger and love for her family, a cast of charming yet dangerous characters, and her own fears, before finally finding her voice.
