After an uneventful month in Paris, K-CIA agents JJ and Maggie think their troubles in the spy world are over. Their first night in Geneva, Switzerland proves them wrong. Not only do they discover two Russian P-KGB kid spies staying at their hotel, but they encounter something even the two of them had not thought possible—UFOs! Deciding to put their extra-terrestrial experience on hold, the two twelve-year-olds focus their attention on the Russian spy kids and discover a complicated gold smuggling operation involving not just the P-KGB spies, but also the Russian mob and a most unlikely group of smugglers, the alien spaceships. Confused about this bizarre alliance, JJ and Maggie team up with a new member of the K-CIA, and the three kids determine to put a stop to the illegal activity. But as they delve deeper into the mystery, things become increasingly complicated and dangerous in this second installment of the JJ Bennett: Junior Spy series.
