In this spine-tingling tale Ingrid Coleman writes letters to her husband, Gil, about the truth of their marriage, but she never sends them. Instead she hides them within the thousands of books her husband has collected. After she writes her final letter, Ingrid disappears. Twelve years later, her adult daughter, Flora comes home to look after her injured father. Secretly, Flora has never believed her mother is dead, and she starts asking questions, without realizing that the answers she’s looking for are hidden in the books that surround her.
