The other side of gold

"Cayden has never really fit in with the other boys in his village. Picked on for his lack of parents and his strange golden eye, he usually keeps to himself, daydreaming about a massive tree towering over a city of white and diamond. Little does he know, the city from his dreams is real. On a quest to discover the secrets of his past, he encounters men made of glittering metal, trees that float through the sky like birds, and new friends who will help him bring balance to a world thrown into war."--Publisher's description.
