Keeper and the Rulership

As the daughter of a landowner, Raneh lives in a world of clearly defined roles and rules. She's supposed to get married, gain status, become a landowner herself, and definitely not have magic. Seeing as it's forbidden and all.
Too bad she has it anyway.
On top of that, a suitable courtship does not seem to be forthcoming, her younger brother is a social embarrassment, her younger sister is better at everything than she is, and . . .
And the Ruler's coming to visit.
