Ever since a car accident tore her family apart, Holly has been part of a lonely-hearts holiday letter–writing club. Each December, she writes to a stranger who is also spending Christmas alone, and receives a letter from another lonely person in return. Usually, the letters go unanswered. That’s the point—the letters are anonymous, and the senders write whatever is in their heart. But this year, the letter Holly receives is different; not only is the letter full of a grief she knows all too well, but its writer, Emma, mentions a place that Holly has visited.

Every December, Josie posts a letter from her home in London to the parents she lost on Christmas night many years ago. Each year, she writes the same three words: Missing you, always. But this year, her annual trip to the postbox is knocked off course by a bicycle collision with a handsome stranger - a stranger who will change the course of Josie's life.

But Bobby, Iris’s best friend, isn’t about to let her hide away. He drags her to a famous autumn street fair in Little Italy, and as they walk through the food stalls, a little family-run gelateria catches her eye—could it be the same shop that’s in an old photo of her mother’s?
