Inside are hundreds of children's drawings.
Each one is signed by a child who vanished from the school decades ago.
At first, the drawings appear to be disturbing expressions of fear and imagination. But when a modern-day murder mirrors one of the images with impossible accuracy, Hunter realizes the sketches may not depict the past.
They may be predicting the future.
As more deaths begin to match the forgotten drawings, Hunter is pulled into a chilling investigation that connects unsolved disappearances, buried secrets, and a darkness that has haunted the town of Oakhaven for generations. With every new drawing decoded, another life may already be marked for death.
Some mysteries are meant to be solved.
Others were never meant to be found.
