My guys have read almost all the above books. (We go through books like water around here.) I'm always on the look out for new books and authors. My kids did read the Hunger Games but only after both dh and I had read them. We talked them over with the kids and they sparked some great discussions. (Still do.) The also read Gregor the Overlander by the Hunger Game author. We also enjoyed the Lloyd Alexander books. (Book of Three, Black Cauldron ect..) We preorder all of Rick Riordan's books (we have kindles and it goes to all of them for the one price.) If you are concerned about the magic then do a unit of Greek Mythology before hand. (It sparked a yearning to learn all about the Greek Myths here. And we talked about how it is different from the myths and what is the same.) If you want a really great list of books go to the Sonlight website and look at the book lists for 6th/7th grades. Sonlight is Christian based and my boys have enjoyed many of the books from their curriculum this year. (Not all but not enough to quit Sonlight.) My sons are very advanced readers and finding books that are still challenging enough to read and are not inappropriate is a challenge.
Oh, I LOVE Lloyd Alexander!!! I forgot about him!!! Be sure to read more than the Prydain books! The Cat Who Wished to be a Man is SO funny!!! And the last one he wrote before he died...The Golden Dream of Carlo Chuchio Carl read out loud to the kids. It was VERY good! Another hard-to-find book that is a classic is called the Chestry Oak. It's about a boy growing up in Eastern Europe during WW2. His dad is a prince, who has been forced to join forces with the Nazis. Everyone thinks he has betrayed his country, but he is actually spying for the Allies. It's hard to find, but I was able to get it on Inter-Library Loan. Well worth the effort, though it might go better reading aloud than having a boy read it himself. I'm not sure Phillip would have stuck with it!
