Let me throw my hat in the ring. I'd recommend Grass by Sheri S Tepper. It felt fresh and original in a way few science fiction books are, the characters are really well done and it just stays with you. Despite being the first book of a trilogy, it works well on its own.

Yes!!! I would also recommend anything by Zenna Henderson.

Now there's a name I hear very rarely...

The best start is Pilgrimage: The Book of the People, especially suitable for a moody teen girl...

(And I wish I could know the story of the Bells of Couvron!)
