350R: Daughter of Lord Leads Resistance to Keep Father in Power (Solved!)

I’m searching for a book that I can only remember the plot of. When I was around 13 I read a book about a girl who was the daughter of a lord. (I’m 35 now, so it would have been written 1998 or earlier). She was poor and was the leader of a small resistance trying to keep her father in his lordship. Eventually she got hurt and captured. She was brought to the capital. To the people she had spent over a year fighting. Once she got there she found that there was far more going on than she realized and the people she had been fighting were their own quiet resistance.

I don’t remember the picture on the front. It was YA, fantasy.

There was one scene that stood out. She received a gift from a “secret admirer”; it was a ring. Which finger you wore the ring on meant different things. She didn’t know that so she wore it on the one that fit.

I borrowed the book from the library and to this day I think about that book. I want to read it again but I can’t remember the title or author.
