'Henry McThrottle suspects that the new girl at school, Roberta Flywheel, is actually a robot on a mission to exterminate all humans. Henry and his friends get Grant Gadget to build a robot-fighting robot which malfunctions and goes completely out of control. Robot Riot! Is a very funny book about robots, making friends and falling out of windows.' Source: www.coop-bookshop.com.au/ (Sighted 23/11/2009).
