Meanwhile, Griffin Bing is locked in the fight of his life with his archenemy, Darren Vader. Both are trying to win an invention contest - and will stop at nothing to be victorious. A runaway dog. Some majorly strange inventions. A mysterious neighbor. A stolen object of great value. These are a few of the ingredients in UNLEASHED, Gordon Korman's latest Swindle mystery.
