Curse Workers trilogy, Holly Black
Cassel Sharpe’s family are curse workers, who can use magic to change others, manipulate memories and feelings just by touch. Cassel, on the other hand, doesn’t appear to have the gift. Or does he? A supernatural series set in a mob/magic world of gangsters and con artists.
