Sixty and single, John spends his days dodging his daughters' unannounced visits to check on his well-being, and the Schultze sisters, who always appear on his daily walks. A self-proclaimed recluse, he prefers to stay home. That is, until a long-lost letter appears, from his best friend and first love, Becca; she is dying and wants to say goodbye.

Every memory that meant anything to him she was part of. Her letters are all he has left.

Every mile, every memory, every letter brings him closer to his first true love; letters filled with treasured and painful memories. Memories that he has buried for more than twenty years—fragile memories of abandonment, betrayal, marriage and death.

Can she forgive him? Can he forgive himself? Or is he already too late?
