In Mal's world, magic is everything. But Mal is a "blank," the anti-magic. Blanks can't be hexed or cursed or saved or killed by magic. And everyone is afraid of them--even Mal himself.
So Mal hides what he is--except from Essie Roe, a witch and his best friend. On the day Essie reveals his secret and casts him out from the only home he's ever known, Mal experiences the true shock of betrayal.
Now Mal travels the world in search of rare, illegal magical relics. When his partner in crime, Boone, hears rumors of a legendary dagger that can steal a witch's power, Mal knows he's finally found his means of revenge. But as the chase for the fabled knife takes them from Boston to Paris to Constantinople, Mal realizes there are secrets afoot that he's only beginning to understand--and all the while the blank monster inside him threatens to escape.
