I just finished this series and I would not allow my 13 year old to read them. In the first book, The Covenant, one daughter conceives out of wedlock. There is a lot of focus on the girls’ season of rumpshringe, when they are allowed to explore outside of their community. Beverley Lewis has books for younger girls. We have one titled, Once Upon a Summer, but I have not read it yet. You may want to check those out. Hope that helps. 🙂
