Age range 9 to 12

Bullied by Zach and his gang, Donovan Richards decides he must learn to defend himself. When he takes his only new friend, Gurveer, along to a martial arts taster class, the boys are told they must take Gurveer's little sister, Abhaya, and her friend, Gabriella, with them. Girls weren't part of his plan, but he has no choice. Will the martial art prove to be like a magic shield? Or will it simply get Donovan into more trouble?
