Cassel Sharp is not a worker. He can't make you luckier, he can't make you happy, and he can't mess with your memories. But the rest of his family can--just not legally.

White Cat takes place in an AU where curse workers exist: rare people who have one type of work they can perform, like give you luck or happiness or even kill you, but to do so is illegal. Enter the crime families, Cassel's brothers, his mother, his friends from school, and Cassel himself -- a smart-mouthed clever teenager whose head is a delight to be inside as he begins to understand his place in the world he lives in and struggles to out-con the conmen.

It's a wild, inventive ride, and I highly recommend the Jesse Eisenberg-narrated audiobook.
