Approached by a stranger, Harriet learns of her estranged father’s death and the fortune she is set to inherit with enough money to pursue her music career full time. But not long after her first night in Bluebelle Manor, Harriet finds herself wandering the halls past midnight, playing mysterious melodies on the grand piano. Something is calling to her, and the secrets they whisper in her ear are frightening and dangerous.
