Oh, I completely agree with simon. I only read one Dragonsong book, but I loved it! (I've never been able to find the others.)
There's also the Redwall series or the Harry Potter series. (I know, I'm still thinking fantasy.) I liked Wizard of Oz by L. Frank Baum and The Grey King by Susan Cooper.
I've also heard that Jacob Have I Loved by Katherine Paterson is good, but I've never read it myself.
