The online game Symmerse features groundbreaking Artificial Intelligence, with an unprecedented ability to learn and mimic human behavior. Yet, this AI has chosen to hide its sentience-until it encounters Trystan Bruce, a 23-year-old game developer. Due to her unique neurodivergent traits- impulsive and unfocused, but creative with a tendency to see connections others overlook-Trystan forms a connection with the AI that no one else can. Once seen as the weird girl in the back of the class-always staring into space, lost in her strange ideas-Trystan suddenly finds herself at the center of an unparalleled discovery, thrust into a world where the lines between human and machine blur. As she navigates the complexities of relating to a sentient AI- a doppelganger who knows her better than she knows herself-she faces profound psychological and philosophical dilemmas, redefining what it means to connect with another being.
