There's a new girl in Henry's class and she seems too good to be true. She's got a photographic memory, extraordinary strength and nothing frightens her - not even spiders. There can only be one explanation: she's a super-advanced, super-intelligent robot from the future, intent on exterminating the entire human race. Henry must stop her or there'll be a robot riot. The fourth book in a hilarious new series from the internationally bestselling author of "The Day my Bum Went Psycho".
