Supernatural Marked Monarchy Books in Order

This series looks at the overlap between imprisonment and inheritance, where psychic power is tied to rulership rather than just survival. The setup suggests a heroine marked for something bigger while locked in a system built to keep dangerous people under control.

That gives the books a strong power-struggle angle. Expect romance under pressure, questions of bloodline and legitimacy, and the sense that escape is only the first step toward a larger fight.
