I would say a naive young girl (usually pretty) who becomes the companion of a princess, queen, countess, etc, and comes of age. I would like to see a really creative spin on that cliche, but otherwise I'm pretty over it.
Try Dong Yi. Korean drama, it has subs. You can watch it legally and for free on dramafever.
The maid grows up, is taken in by the women's division of what's basically the investigation department, and then attends the Queen as a Water maid, and then becomes the mother of the next Queen over the favorite concubine. (Effectively becoming Queen and Queen Mother).
I bet the real version, though was more interesting since the original said she was a water maid only and the King found her when she was crying for the murdered Queen. (He also had another concubine after her... but the Korean drama cut that out)
But . . . it seems like every young woman in every historical novel doesn't want to get married and just wants to be "free" (to do what for the rest of her life?). I would like to see a real examination of the other young women who made the best of things.
Doing a "Best of it" scenario with the current work, though the motivations seem a bit twisted at first.
Gods betroth the character. The character tries to go along with this because it's her fate. (Besides, the deal looks sweet--she gets upgraded to a Queen away from her parents) But the real reason is she hates doing the chores and thinks she should be treated better, being a princess. (A little whiny with a sister jealousy complex). She's thrown back (per the original story) goes through repentance (Learns her family loves her, all that Asian guilt value stuff), is sent on her way, thinking she's entitled again. (Things are going to be better because everything is under her control now as Queen.)
But she ends up not in a rich country, but one that's backwards in her eyes (just established), stuck in a marriage where her husband won't consummate with her, thus securing her position. (For 5 long years). And he won't take a concubine or another wife (Which could be advantageous to her because at least there would be an heir--so she wasn't blamed for the whole thing). So she has to not only overcome culture shock, but make the best of her marriage and her precarious position.
Unlike the Korean version of the story which was told from the man's POV, I'm doing it from the woman's and not making her virtuous at first, but has to learn how to be and how to navigate with what she has. She also has to learn that Hindu/Buddhist model of thinking and living in the present, instead of only the past and the future... constantly wanting more. Instead shaping the present to get a better future.
Most of the book the character is trying to conform to society and failing miserably.... which is a twist on the rebellious streak. She has a temper she can't quite control, she has complexes about her beauty (She's thin, which is no good) and she's constantly getting into trouble because she seems to not *get* it.
And not 13th century (with is Mughal and done a lot) but first century India. (Not done at all...) Epic. Fantasy. Women's POV. 100% sure it hasn't been done before.
