Book excerpt: Key Selling Points In Heart Sister, a teen filmmaker, reeling from the loss of his twin sister, tries to track down the recipients of her organs. Explores themes of grief and loss and how families cope in the face of inconceivable tragedy. Governor General Award–winning author Caroline Pignat describes it as “raw, real and riveting...a powerful story of hope.” The author is also a screenwriter, which is reflected in the book’s unique structure. A few years ago, the author's brother received a new heart. This story is written in gratitude to the (still anonymous) family of the young woman who gave him a new lease on life.
