Silenced. The Hollowverse

They said her mother was insane and that her sister was gone, but both were wrong. Years ago, her sister disappeared without a trace-no struggle, no explanation, just an open window and a streak of blood. Her mother was blamed, institutionalized, and forgotten, but she always knew there was something more lurking beyond what anyone would admit. Returning to the decaying house she once called home, she finds whispers in the walls, strange symbols in old journals, and evidence that whatever took her sister might not be done.
As the past pushes into the present, she begins to doubt her memories, her sanity, and whether she is truly alone. This is a story of psychological horror and supernatural dread, about the cost of knowing the truth and the terror of being the only one who remembers it.
