Its based on a book series I absolutley loved in middle school, I might wanna pick it up again and read it a second time. But it started with a 5 book series about merlin's youth around 12-17 years old and how he got to learn all that he did. The 5 book series (Lost Years, Seven Songs, Fires, The Mirror, and The Wings) are the ones I have read, I think that "The Mirror of Merlin is probably the best one. But anyways, apparently the author is working with disney who has assembled a team for "Merlin: The Movie"
