This is a love story. It's the story of a second-hand bookshop called Howling Books where people leave letters to strangers, or those they love, or want to love, between the pages of books in the Letter Library. Henry Jones and Rachel Sweetie are best friends. Or they were. Before Rachel moved away to the sea. Now, she's back, grieving for her brother Cal who drowned in the sea that he loved. Rachel loves Henry. Henry loves Amy. Amy loves Amy but is happy for Henry to love her too. This is a book about books. About the power of literature to cradle our past, present and future selves. It's about how we leave ourselves behind when we die. How we leave our histories in the things we love - like books.
