Here are all the details I can remember:
It was a picture book, but one with medium to a lot of words. I read it between 1990-1992, and I think it might have been a new copy, but I have no idea when the copyright was. I remember really loving the pictures!
It was a story about a little princess who is so loved by her father, but she is spoiled rotten and for her birthday he hires some gypsies to perform for her. She throws a fit over something and then, after she’s supposed to be in bed, she overhears him say that he wishes she would be a sweet girl (possibly like one of the gypsy girls?) or she will not be fit to run the kingdom.
She either runs away or is taken by the gypsies, and they live a life of hard work and expect her to do it too. After only a little while, she fits right in and her skin turns brown from being out in the sun, and she almost forgets about her former life.
The gypsies perform for lots of people, and they teach her to perform too. One day they go to a castle that seems familiar, but it isn’t until she sees her father that she remembers her previous home. She runs to his arms and he commends her for learning to be good.
Anyway, that’s about all I can remember. I hope you can help!
