Katrina is never alone. She is bound to others inside her, tighter than any Siamese twins could ever be: Cherry, the freewheeling photojournalist, Anisa, the covert spy-assassin, and others as yet unknown, all sharing her body and mind as she goes about her work in a psychiatric hospital. But she is starting to unravel, and her sole hope is the handsome Dr. Sean Paisley, the only one who can make her whole again. Girl Within Girl is a dark erotic thriller that wanders through a sensual maze of manipulation and mind control.
