Greybridge is a city built on quiet streets, forgotten bridges, and shadows that linger long after the lights go out. By day, its river reflects rooftops and passing clouds. But at night, when the silence grows too still, the city reveals what it has buried-echoes of lives interrupted, memories that refuse to fade, and truths that reshape themselves each time someone tries to forget.Lena Corwell has learned how to preserve the past without touching her own. As a conservator of old photographs and historical documents, she restores other people's memories while living a carefully controlled life above the river. That fragile balance shatters the night she hears a knock coming from the wrong side of a locked door-one that should not exist.Soon after, her younger sister Emma, missing since childhood, returns. Unharmed. Unchanged in body-but altered in ways Lena cannot explain. Emma speaks of a hidden layer beneath the city: the Echo-City, a shifting maze of reflections, unfinished streets, and memories left behind. A place that remembers what people try to forget. And one that knows Lena intimately.As strange lights flicker across the river and a silent, faceless presence appears in mirrors and glass, Lena is forced to confront a truth erased from her past-a night that shaped Greybridge itself and bound her to the Watcher, a being trapped between memory and reality.THE ECHOES OF GREYBRIDGE is a haunting psychological supernatural thriller about memory, trauma, and identity. Atmospheric, emotional, and unsettling, it explores what happens when the past refuses to stay buried-and when a city becomes both witness and guardian of the truths we are not ready to face.
