As a teen, Andrew Richardson had an imaginary friend named Adiho-only she wasn't the comforting kind. Adiho was cruel, manipulative, and dangerously unpredictable. Now, years later, Andrew has buried those memories, dismissing them as childhood fears.
But when his young daughter, Peyton, begins speaking to someone no one else can see-someone named Adiho-Andrew's past comes rushing back. As Adiho tightens her grip on Peyton, Andrew must confront the sinister force that once haunted him before his daughter falls victim to the same nightmare.
