Seventeen-year-old Hanna has been in love with Seth for as long as she can remember, but now that her feelings are requited and she and Seth are in an actual relationship, it feels like love just isn't enough. Seth is controlling and all they seem to do anymore is hurt each other. If that's what love is, Hanna doesn't want any part of it.

Besides, she has something else on her mind: graduation. But she's been ignoring the school's community service requirement for years, and now she needs to clock in some hours in a hurry. She volunteers as a caretaker for the Schoenmakers, an elderly couple who live on a farm behind Hanna's house. Mrs. Schoenmaker has advanced Parkinson's, and her husband can't always be there to watch over her.

While caring for Mrs. Schoenmaker, Hanna gets drawn into an audiobook that the older woman is listening to, a love story of passion and sacrifice and shared hurts and complete devotion. She's fascinated by the idea that love like that can truly exist, and without her even realizing it, the story begins to change her.

But what Hanna doesn't know is that the story she's listening to is not fiction - and that Mrs. Schoenmaker and her husband's devotion to each other is about to reach its shattering, irrevocable conclusion...
