Even worse... Jamie hasn't told Mae a thing about any of it. Mae turns to brothers Nick and Alan to help her rescue Jamie, but they are in danger from Gerald themselves because he wants to steal Nick's powers. Will Mae be able to find a way to save everyone she cares about from the power-hungry magician's carefully laid trap?
