Reign or ShineUnknown - 2009
As if trying to fit in at a new school isn't stressful enough, sixteen-year-old Nikki Donovan just found out that her long-lost father is, in fact, the demon king of the Shadowlands--the world that separates and protects us from the Underworld. When she is brought there by the mysterious--and surprisingly cute--messenger Michael, she learns that her father is dying, and he wants her to assume the throne. To complicate matters, a war is brewing between the Shadowlands and the Underworld, her half-demon qualities are manifesting, and her gowing feelings for Michael are completely forbidden. Ruling a kingdom, navigating a secret crush, and still making it home by curfew--what's a teenage demon princess to do?
