White Cat is the first book in The Curse Workers series about Cassel Sharpe, written by Holly Black.

Now seventeen, Cassel finds himself sleepwalking up on the roof at his prep school, dreaming of a white cat and nearly dies getting back down.

This bizarre occurrence, the strange behavior of his brothers, and overheard conversations make Cassel suspicious that he's being manipulated, and he goes to a fortune teller to get amulets to protect himself from memory alteration, which he cuts and conceals inside his leg.

Shortly after, he discovers that one of the rocks under his skin has broken, and that his second oldest brother Barron has been manipulating Cassel's memories.

He demands she undo it, but his mother claims she cannot, and Cassel realizes that he was a mark himself, gullible enough to believe that Lila would forgive him and love him so easily.
