It's a good list. I absolutely Loved the Bartimaeus Trilogy by Stroud and anything by Diana Wynne Jones is just ambrosia. Many people have told me to give A Wrinkle in Time a go over the years ... anyone else read the series?
One of the commentor's recommends Tales of the Otori by Lian Hearn ... I'd have to agree with him ... the fact that Nightingale Floors really exist astounded me. I'd love one of those, but then the adorable mutts would never shut up!
