The Green Ring Conspiracy (Adventures in Odyssey #53)

"It all begins when a small plane crashes under strange circumstances outside town. The mystery deepens when a backpack filled with money is found in the woods near Gower's Field, outside of Odyssey. What does all this have to do with the Green Ring Conspiracy? Whit, Eugene, and Connie have to put together the clues before it's too late to stop a worldwide conspiracy!"--Container.
