After narrowly surviving a vicious knife attack, gangland detective Eoin Miller thinks he’s earned a break from hunting down thieves, runaways, and stolen drug money. But when crime boss Veronica Gaines tips him off to a particularly sensitive new case, his Romani blood won’t let him say no. A rapist is targeting immigrant girls, and Eoin knows all too well just how little help an outsider can expect from the local police. Besides, his client isn’t looking for someone to arrest the bastard. He’s looking for someone to stop him—for good.

But the deeper Eoin digs, the more tangled he becomes in a web of corruption, racism, and revenge…especially once his troubled past threatens to derail the investigation by raising questions about his own loyalty and family ties. With his life teetering on the brink of disaster, Eoin realizes there is a fine line between justice and punishment. Now it’s up to him to decide just which side he’s on.
