A sweet scent leads an amnesiac young woman to a horrifying discovery: a ghoul feeding on a human body—and a hunger within herself that she cannot explain. With no memory of her name or past, she accepts shelter from Sam, a kindhearted protector sworn to defend humanity against ghouls. He gives her a home and a new identity: Maggie Tinker. For a brief moment, she believes she might be safe.
That fragile security unravels when an encounter with a ghoul gang reveals another name: Willow Shainsu, their missing queen. While Sam sees someone who needs protection, the ghouls recognize a leader they are desperate to bring home. Caught between their conflicting claims, Maggie struggles to understand her unnatural abilities, her thirst for blood, and the people who insist they know her.
After a near-fatal fall triggers fragments of memory, she recalls a bloodstained room, a locked door, and a desperate decision whose consequences remain unknown. Each recollection complicates the distinction between protector and monster—and raises the possibility that her forgotten past was deliberately taken from her.
