Maryam has endured unrelenting terror since birth. Mysterious letters appear before her—no matter how many times she burns or discards them, they always return, as if they possess their own will. She realizes she is not alone. A supernatural entity has bound her with a dark promise, whispering words only she can hear and following her every step. The harder she tries to break free, the more tightly the unseen shackles ensnare her—until she no longer knows whether she is truly alive, or merely possessed by the entity forever.
