Mexico Fever — George Wier

Former Governor Dick Sawyer may be dying, but he has one final mission for Bill Travis. Bill has to fly to Pisté, Mexico, to find Walt Cannon, friend and retired Texas Ranger who disappeared while on the trail of a man named Sunlight -- a ruthless killer, drug lord, revolutionary and cult leader. Sunlight wants to return Mexico to the rule of the ancient Maya, but between the jungle and the ruins of a civilization long dead is the most dangerous animal of all -- the Mexican Army. With the help of a Mexican police captain, a little girl, and an ornery donkey, Bill Travis must go toe-to-toe with his most dangerous enemy yet in order to save a friend.
