Have you tried the Philip Pullman His Dark Material trilogy, the first one is the Northen Lights. It was made into that bad movie, The Golden Compass with Nicole Kidman, but the books are better.

Also, the Eragon series is ok too, although still waiting for the final book to come out.

I'm happy to hear that the next book in the Obernewytn series is coming out, I've been waiting and waiting for that one!
