When she accidentally donates her favorite book—a heavily annotated copy of To Kill a Mockingbird containing a memento she can’t be without—to a local little community library, she’s devastated. But then the book turns up a week later, back in the library with fresh notes in the margins, along with an invitation in a copy of Great Expectations to meet her newfound pen pal. A life-changing conversation, written only in the margins of beloved classic books, begins between Erin and her Mystery Man.
