For a haunted house to be born, somebody has to die. In the sleepy coastal town of New Castle, New Hampshire, seventeen-year-old Billy Hasler's life is about to take a terrifying turn. When his best friend David Spivey inherits a mysterious house on a nearby island, it seems like the perfect place to spend their final summer before heading off to college. No parents. No police. No responsibilities. As they dig into the island's dark past, they awaken an ancient evil that has influenced generations. What begins as an innocent summer adventure quickly descends into a nightmare. "Something I Keep Upstairs" is a haunting exploration of friendship, sacrifice, and the darkness lurking just beyond our understanding.
