Another Newberry book

I don't know how I never read Plain Girl as a child, but somehow I missed this book, and I loved it! The copy I read was from the library in the drab 1950s cover, the same copy in our library for 50 years, so maybe that's why it didn't appeal to me as a child. It's a book about how an Amish girl goes to school and she's fearful of the "first step away" that will spiral her out into the non-Amish world.
