Or here's an awesome one. The Chronicles of Icemark, though don't forget to read The Seven Realms novels by Cinda Williams Chima, Or to pick up the Fairyland Series by Catherynne Valente. OH THERE ARE JUST TOO MANY GREAT BOOKS TO READ!
I thought Blue Fingers was really cool. It was fascinating to look at their take on the ninja. I especially liked how the main character develops. It's less about the ninja or portraying them "accurately" (though they do pretty well) and more about Blue Fingers himself and his story.
