The old photo album lay open on the kitchen table, its brittle pages whispering as Amelia gently turned them. Sun-dappled images of her childhood flooded her senses: her mother’s smile, her father's boisterous laugh. Each picture held a memory, a warmth that spread through her chest. The aroma of freshly brewed coffee, a morning ritual she shared with her dad, mingled with the scent of aging paper. A letter, delivered just yesterday, sat beneath the album. It spoke of a brother, a half-sibling she never knew existed. The stranger's existence felt like a misplaced puzzle piece, a missing piece of the family portrait.

The chill in the autumn air seemed to sharpen the colours of the past. Amelia reached for a chipped mug and took a long sip, her gaze drifting out the window. The trees were painted in fiery hues, the leaves mirroring the warmth she felt looking back, and the uncertainty of what lay ahead. She thought of her father, how he would have reacted, of the stories he would have told.

She picked up the letter again, the handwriting unfamiliar. A wave of unease rippled through her. She felt like a child again, uncertain and alone, yet the echo of a forgotten life called out to her.
