Unleashed

Luthor, a former attack dog, is supposed to be on his best behavior now that he's in the care of Savannah, a girl who's easily a dog's best friend. But every time a certain truck passes by Savannah's house, Luthor goes into attack mode, and chaos follows. 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, the seventh of Gordon Korman's Swindle mysteries. Like a Doberman with a mission in mind, there's no holding this story back!
