Can one boy use his recast powers to save the world?

JD is a young boy raised by his grandfather to be the last hope for a world in conflict—but too bad nobody told JD! He's not the best student in school, and he's way more interested in the hottest new magical weapons than any conflict between good and evil. So when assassins from the Fourth World make their way up a living waterway to JD, will he learn to master the powers he's been entrusted with? Or will his adventure end before it begins?
