Twelve-year-old Sophie is reading to her blind grandfather when she discovers an old letter hidden in a forgotten book. As she reads the letter, she uncovers a heartbreaking love story and a secret that could change everything.

While reading The Count of Monte Cristo to her grandfather, Sophie finds a faded red book in the closet. Her grandfather reveals it was a gift from his first love, Margaret, whom he never married. Sophie reads the book aloud, and a letter slips out. The letter is from Margaret, explaining she left Walter because she was going blind and didn’t want to burden him. Sophie’s grandfather, who thought she had moved on, is devastated.

Determined to help, Sophie convinces her parents to visit the address on the letter. They discover Margaret lives in a care facility, and they arrange a reunion. When they meet, Walter and Margaret reconnect, reliving their lost love. Sophie learns that some love stories never truly end—they just wait for the right moment to continue.
