I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
I remember a comic book that I owned as a child, telling the story of the Swan Princes. I read it over and over and over again.
This is an excellent re-telling of that old tale.
