“Three, two, one, go!” the ranger yelled. In a blaze of speed, twenty-five teams of bikers took off as fast as they could, heading straight into the heart of Shark Valley.

With keen eyes and quick thinking, they discover a get-rich- quick scheme that quickly becomes unglued. Join the twins and new friends in a suspenseful journey into the Everglades.
