i think it's a good book if you think you might not be too immature i say you should read it, of course it might not be able to be read by smaller kids but I'm 12 and i think it is a good book because, it has a good cause and if you have a good imagination it will be a good fit for you.
This book I would reccomend to everybody at a high school reading level if they are interested in sci-fi/fantasy books. its a basic "youre the chosen one" stories.
