Filling In The (Fantasy) Gaps

I'm discovering lately that I seem to have missed out on the fantasy phase in my youth. (I was big on horror, sci-fi, and contemporary as a kid, like Stephen King, Christopher Pike.) There seems to be all these sort of common knowledge things for people who have read a lot of fantasy that I have no idea about and I don't like that. It's like I'm missing a whole layer of experience that could enrich my writing so I've decided I'm going to fix it. Here's what I've come up with so far:



The Dark Is Rising Sequence by Susan Cooper
The Queen's Thief series by Megan Whalen Turner
The Wrinkle In Time Quintet by Madeline L'Engle (Already read A Wrinkle In Time)
Terrier by Tamora Pierce
The Hero and the Crown by Robin McKinley
Abhorsen Trilogy by Garth Nix

I would love some high/alternate world fantasy recs! I've heard good things about Diana Wynne Jones, Shannon Hale, as well as Robin McKinley and Tamora Pierce's other books but they have so many that I have no idea which book to choose. I'm especially attracted to stories based in mythology or folklore, and I love anything with magic, but I'll read anything that's well-written! That includes Middle Grade.

Note: I've already read The Lord of the Rings Trilogy, Graceling, and Fire is in my TBR pile, I'm up to The Voyage of the Dawn Treader in the Narnia chronicles. So please, rec away!
