On these two recommendations, I'll give Lightyear a try.
Turning Red--A number of people do mention that the central metaphor is about menstruation. Although all of the victims of this curse are female, and it is called "the curse" a number of times, I disagree. There are women who would be in menopause who make this change. And it has more to do with these women's emotion, especially anger. Because women especially need to control their emotions, I think the curse occurs when they have uncontrolled emotion, whether on purpose or by accident. This would frequently begin happening in adolescence. This just makes more sense to me, especially because menarche was specifically mentioned and rejected as an explanation.
