I discovered this book when I was looking through all the banned books materials at the American Library Association's website and decided to randomly choose it as a book to meet this challenge. I'm really glad I did, as I discovered that this book was originally written in French (the author is from China originally, but now lives in France and writes in French) and it was made into a movie (which I will have to make a point of seeing), making it eligible for the French Bingo Challenge and the Diversity on the Shelf Challenges too.
As I've said before, one reason I like joining reading challenges is because I so often find cool books that I would otherwise not have heard of, like this book. It's a short book and it was a deceptively fast read, but the themes of censorship (yes, it's kind of ironic that a book with that as one of its themes is itself a victim of censorship), and the transformative power of good literature, are deep and well done. I know that I will be thinking about this book for a long time, asking myself exactly what the relationship between Balzac and the titular seamstress is - anything more I say will venture into potential spoiler territory. Sufficient to say this book is highly recommended and I would love to discuss it with anyone else who has read it!
If you're curious, the ALA banned/challenged books report for 2004 - 2005 has more info about the banning of this book.
