Cass and her mom have always stood on their own against the world. Then Cass learns she had a grandmother, one who was never part of her life, one who has just died and left her and her mother the first house they could call their own. But with it comes more questions than answers: Why is her Mom so determined not to live there? Why was this relative kept so secret? And what is the unusual mask, forgotten in a drawer, trying to tell her? Strange dreams, strange voices, and strange incidents all lead Cass closer to solving the mystery and making connections she never dreamed she had.
