Some sessions are meant to heal. This one was meant to destroy. When Evelyn first sits across from him, she believes she's in control. She's the professional. The therapist. But Lucas isn't here for help-he's here for her. What begins as a game of words and stolen glances soon turns into something far darker. Lucas knows every fear she hides, every desire she denies, and he's patient enough to strip away her defenses one by one. With each meeting, Evelyn is drawn further into his world-where danger feels like safety, and surrender feels like freedom. But obsession cuts both ways. And by their thirteenth session, only one of them will be in control. SESSION 13 is a dark, erotic psychological thriller about power, seduction, and the moment when prey decides to become the predator.
