You could try comics books. I haven't read this one
https://shannonhale.com/books/diana but I've liked other books by the Shannon Hale, and I've heard good things about this.
"Princess Academy" by Hale is also very good. It's a fairy tale type of book: When the prince of the realm is old enough to marry, the priests consult various omens, and decide where in the kingdom the new queen shall come from. Normally the prince goes there, attends a few balls, and picks some suitable noblewoman, but this time the priests have chosen a really poor, remote village. So a tutor goes there to teach all the unmarried girls the basics needed to qualify for princess: Dancing, deportment, conversation... and also reading, diplomacy, economics. It turns out it's not a book about a poor girl marrying a prince, it's about poor girls getting an education, and how that affects the whole village. I liked it a lot.
