The series I obsessively reread were the L. M. Montgomery books--although they actually are a bit pulpy in bits, they're pretty high quality. I was also not a fantasy or sci-fi kid, though I logged some time with Hitchhiker's Guide (so funny), Susan Cooper (wish I could get DD to read these!) and Tolkien. DH also had no interest in this stuff at all. So DD may be in uncharted territory if this is where her interest goes, although my brother is a huge Tolkien nerd.

She will love Watership Down, I'm 100% sure. But it's dark and sad in places, IIRC. I don't know if she's ready.
