French book HELP! EMEGENCY!!!?

I have a french book report due really soon and I haven't read the book (because it is way too boring). The book is L'ile de Black Mor by Jean-Francois Laguionie. I really need a full summary of the book. I know the book is a movie too, if any one can find it on the net (preferably with subtitle that are english) it would be really useful. THXX!
