Nelson is the last ninja in the world, but no one knows it. Well, almost no one. One thing is certain: at school Nelson is one of the worst kids in sports. All that is about to change right now, with his new ninja powers. But precisely at the most worthwhile moment, when Nelson is about to win all the competitions, a strange thing happens: he becomes his grandmother! How does the last ninja boy in the world manage to save the day (and his friends too)? * Ninja Boy, the hit series written by Anne Doe and illustrated by Jeremy Leigh, was a resounding global success. Coming soon - the fourth book!
