I'm hoping someone has some knowledge of Garth Nix, and in particular the Keys to the Kingdom series. I'm trying to find books for my DD. She loves fantasy/magic. She loved HP, Diane W-J, has read the Hobbit and got bored with Lord of the Rings. Her current favourite is probably anything Percy Jackson/Rick Riordan.
I was looking on Scholastic for suitable books, and the Garth Nix series was suggested. They suggested US grades 3-7, which would be perfect for her. However, I just wanted to find out if anyone had read them and had any views (also it would be good to know if they are any good!). Thanks!
