Some promises are meant to be broken. When Josie’s sister Megan spirals into addiction, she makes a sacred vow: if anything happens to Megan, Josie will take care of her young son, Sunny. Three days later, Megan is dead–and Josie’s promise becomes a life sentence. Haunted by guilt over failing to save her sister, Josie welcomes her troubled nephew into her home. But as the initial shock of grief fades, unsettling questions surface. Megan wasn’t alone on the night she died. Was it really her addiction that killed her, or something more sinister? As her family begins to fracture, Josie feels her grip on reality slipping. Strange incidents multiply. Items disappear. Whispered conversations stop when she enters rooms. Is Sunny’s presence causing these disturbances, or is Josie’s guilt-ridden grief making her paranoid? When the people she trusted most begin to doubt her stability, she’s forced to question everything she thought she knew. Because some promises don’t just bind us–they blind us to the truth. A claustrophobic psychological thriller about family loyalty, deadly secrets and the price of keeping your word, perfect for fans of Lisa Jewell and Shari Lapena.
