Nightingale is human - or would be, had it not been for the manner of her creation. Genetically engineered and grown to adulthood in a lab, she was created, not born. Why? For the sole purpose of the entertainment of rich men as one of the many Inamoratas in the bordello business .

She's been able to see ghosts since her mother tried to murder her when she was five years old. No way does she want anyone to know she can talk to spooks. Being a foster kid is hard enough without being labeled a freak too. Normally, she just ignores the ghosts and they go away. There's a little glitch this time. The ghost she sees is her foster sister, Sally. Everyone thinks she's just another runaway. Mattie knows the truth, though-she's dead, murdered. Foster kids look out for each other and Mattie feels like she has to help Sally, but she can't do it alone. Against her better judgment, she teams up with a young police officer and together they set out to discover the truth of Sally's disappearance. Now the killer has set his sights on her. It becomes a race to see if she can find the truth before the serial killer finds her.
