From the New York Times bestselling author of the Falling Kingdoms series comes the first book in a brand-new duology about forbidden magic and dangerous secrets, for readers of Victoria Aveyard and Margaret Rogerson.

Josslyn Drake knows only three things about magic: it's rare, illegal, and always deadly.
 
So when she's caught up in a robbery gone wrong at the Queen's Gala and infected by a dangerous piece of magic--one that allows her to step into the memories of an infamously evil warlock--she finds herself living her worst nightmare. Joss needs the magic removed before it corrupts her soul and kills her. But in Ironport, the cost of doing magic is death, and seeking help might mean scheduling her own execution. There's nobody she can trust.
 
Nobody, that is, except wanted criminal Jericho Nox, who offers her a deal: his help extracting the magic in exchange for the magic itself. And though she's not thrilled to be working with a thief, especially one as infuriating (and infuriatingly handsome) as Jericho, Joss is desperate enough to accept.
 
But Jericho is nothing like Joss expects. The closer she grows to Jericho and the more she sees of the world outside her pampered life in the city, the more Joss begins to question the beliefs she's always taken for granted--beliefs about right and wrong, about power and magic, and even about herself.
 
In an empire built on lies, the truth may be her greatest weapon.
