The Monster Within is a chilling psychological horror novel that blurs the line between madness and the supernatural. When trauma psychologist Dr. Mara Ellison returns to her late mother's secluded estate, she intends to find closure. Instead, she unearths whispers of an ancient evil—and something festering within her own mind.

As strange voices echo through the walls, terrifying visions plague her sleep, and gaps in her memory widen, Mara is forced to confront a horrifying question: is she haunted by a demonic entity... or has her grip on reality finally snapped?

Told with mounting dread and layered twists, The Monster Within explores the darkness buried in memory, the terror of losing one's mind, and the chilling realization that the most dangerous monsters don't always live under the bed—sometimes, they live behind your eyes.
