Asked by elisa89 on Tue 10, Jul 2012 01:37am :

I'm looking for a book for the past 8 years!
Is a book about a young French woman of 1700 who married a Spanish
nobleman, which disrupts its ways, for example, allows you to read all the
books you want or require it to take a bath more often than French culture
at the time allowed.
She slowly falls in love but in the end he dies in battle.
I remember only there things!
 
please help me find this book, I know that there are in French and English!

thanks
