“Just One Jew” by Moishe Mendlowitz
And there’s a biography of Rebbetzin Vichna Kaplan that came out recently that is really good. I think you would like it. It’s called “Rebbetzin Vichna Kaplan”. She was the founder of the original Bais Yaakov in America. It has lots of stories about the school and the girls, and it was very interesting.
