The police serve the law. Zady Proya serves the victims. In the dark underbelly of Sydney, there are problems the cops can't touch. For those, you call a Hidden Hand. Zady Proya is the best there is: part investigator, part enforcer, and entirely dangerous. She fights her own demons with a bottle and a fist, but she fights for others with a brutality that leaves men broken. When a wealthy socialite's daughters vanish without a trace, Zady and her partner Beefa-a bearded mountain of ex-military muscle-tear the city apart to find them. But this isn't a simple kidnapping. As they peel back the layers of Sydney's elite, they uncover something ancient, rotting, and terrified of the light, and Zady is the only thing standing between the girls and the fire. She's broken, she's high, and she's absolutely lethal.
