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 realises 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.
