Something is wrong with the voice in her head. At first, it feels like a passing thought-something easy to ignore. But then it starts finishing her sentences. Correcting her decisions. Speaking at the wrong time... in her voice. Soon, hours begin to disappear. Texts are sent that she never typed. Conversations happen that she doesn't remember. The people around her start noticing a change-and some of them seem to like this version of her more. But the most terrifying part isn't losing control. It's the realization that the voice isn't random. Becoming better at being her than she is. As reality fractures and memory begins to slip, she's forced to confront a question more disturbing than any nightmare: What if the thoughts in your head were never yours to begin with? And what if the real you is the one that doesn't belong? The Person in My Head is a chilling psychological horror story about identity, control, and the terrifying possibility that something inside you is waiting to take over.
