In an empire built on lies, truth can be our greatest weapon. Jocelyn Drake knows only three things about magic: it is rare, often illegal, but always deadly. One day, as a result of an unsuccessful attempt to steal a box, forbidden magic penetrates the girl’s blood, which allows her to immerse herself in the memories of the famous dark sorcerer. Now Jocelyn needs to get rid of the magic before it destroys her soul. But in Ironport, all witches and wizards end up in the Prisoner's Fortress, and attempts to find help can lead to a death sentence. And there is no one Jocelyn can trust. No one except Jericho, who offers her a deal: his help in exchange for power itself. But Jericho is not who he says he is. And the closer they get, the more Jocelyn begins to doubt good and evil, power and magic, and even herself.
