A giggle escaped Amelia's lips as she flipped through the album. She’d always loved a good mystery, and today, she’d hit the jackpot. The attic had yielded a treasure trove of forgotten memories. She bounced slightly on the balls of her feet, an involuntary movement of pure delight.

She paused, studying a faded photograph. Her great-aunt Margaret, the woman known for her quiet demeanor and love of needlepoint, was pictured on a motorcycle, wind whipping through her hair, a huge smile plastered on her face. The caption below stated: "Margaret and the boys, road trip '52." Amelia's jaw dropped.

She began to wonder if maybe she had to revise the family history.
