The reason for the hatred is a dangerous secret owned by supergirl Kiki Strike and her assistants. The fact is that under modern New York there is a secret New York, a Ghost City, built by a criminal community more than two hundred years ago. And anyone who has access to its tunnels can easily rob any bank, museum, store or mansion. In order to prevent a new generation of criminals from entering the Ghost Town, Kiki Strike and her team are on guard. Supergirl Detective - bestselling superbook!
