If love lives between the lines, then memories are in the words. To Henry, Howling Books is more than his family's second-hand bookstore in Gracetown, Australia. It is The Letter Library, a collection of people that hide traces of themselves in letters left between book pages. Alternating narratives, Rachel explains how she used to feel the same way. That is until the day before she moves. Using the Letter Library, she confesses her love to Henry. Their friendship is over. Then Rachel's brother drowns. Things fall apart. Reunited in Gracetown, Henry and Rachel realize that friendships do not break easily.
