Query: A truly great book - especially for teenagers

I first read this book when I was 15 years old and it absolutely captivated me. I read it again 25 years later, and it was just as magical. I have never forgotten the bittersweet ending, and just the other day, picked it up and read the last few pages again, and was filled with emotion. Highly recommend this book to anyone who enjoys fantasy - this is as rich as Lord of the Rings, in a different fashion.
