Seven-year-old Abby didn't kill her own sister, her imaginary friend did. Why would no one believe her? Abby thought she had buried the past-until her young daughter begins speaking to someone no one else can see: Ally, Abby's twin sister who died decades ago. Plagued by haunting memories, Abby's unease spirals into terror when she uncovers a chilling secret. The discovery shakes loose a horrifying possibility: maybe she wasn't the one who killed her sister after all. Maybe it was her imaginary friend. The real killer could still be out there, and the only way to clear her name and bring her sister peace is to prove her memories are more than just nightmares. But in Abby's family, innocence is never simple. Every generation is cursed with a 'good' twin and a 'bad' twin-a legacy steeped in jealousy, betrayal, and unspeakable tragedy. Determined to break the cycle, Abby must unravel long-buried secrets, enlisting the help of estranged family members and the one person she swore she'd never rely on again-her ex-husband. As sinister threats creep closer, Abby realizes that protecting her daughter means confronting the darkness that has haunted her family for generations. The truth could set her free-or destroy everything she loves.
