The survivor of a college dorm massacre, a woman accused of her lover's murder, Madeline Hewitson is haunted by ghosts and tormented by a killer only she can see. A seasoned military veteran, Jacob Denisov lives alone in his small, darkened home, sleepless, starving, and angry. When neighbour Madeline drives her car through the front wall of his house, she breaks his life wide open. Jacob watches Maddie, recognises a kindred spirit and wonders what she fears more than herself. Has someone caught her in a twisted labyrinth of revenge and compassion, guilt and redemption, murder and madness? When Maddie's imaginary killer takes form, she fights back. But will she be strong enough to triumph, or is the killer she fears no more than a shadow, an illusion...that watches?
