Romain Rolland is not very well known in Japan, but he is a Romantic literary giant on par with Victor Hugo. This is a story about a single mother, which was still socially unusual in France at the time. I think it's a book that allows all women to be reminded of the deep love and strength they secretly possess through the protagonist. I bought it used, so there are some yellowing and small stains, but I think it's valuable as it is already out of print.
