Dream Casters: Shadow by Adrienne Woods

Chastity Blake discovered the hard way what she was: a modern-day Sandman. But things arent looking up for Chastity. She is guarding a secret deep within her — her dark sand, or what Reverians call her Shadow. Shadow Casters are known for their dark dreams, the nightmares they create. If shes caught with dark sand, she may be subjected to harsh interrogation, even banished to the Oblivion with the other Shadow Casters... and that is SO not on her list. Will she be able to hide her darkness from the most powerful Somnium alive? How long can she outrace her destiny before true nature catches up with her? Shadow Casters is the follow-up of bestselling author Adrienne Woods second series, Dream Casters.
