The Perfect Thrillers Collection

When Anna and David adopt twelve-year-old Mia, it feels like their family is finally complete. She's polite, intelligent, and eager to please—everything they'd hoped for. But when Mia's behavior toward Anna turns cold and unsettling while remaining perfect for David, cracks begin to show. Small accidents around the house, strange conversations, and moments that don't add up leave Anna questioning her own sanity. As the tension builds, she realizes that bringing Mia into their home wasn't just a mistake—it might destroy their family forever.
