"His Dark Materials" by Phillip Pullman.
It's actually a trilogy, and the first one is called "The Golden Compass," and it at first seems a bit juvenile, but the second and third books ("The Subtle Knife" and "The Amber Spyglass") are more serious.
I would also suggest "The Memory of Earth" by Orson Scott Card. Most people know him for the Ender series, but this book, and the ones that follow it, are just as good, and are also chock full of those wonderful moral dilemmas that are in the Ender books.
