A plane crash! Lost in the jungle! Hunted by their old enemy, will Adam, Justin, and Kim survive long enough to find the Third Stone of Power? With only a young boy, Tukum, as their guide, the kids make their way through the dense and dangerous jungle to find the lost city of stone gods, where the Stone of Power might be located. River rafting on a crocodile-infested river and evading predators are just part of this hazardous task. Of course, their old adversary Dr. Khalid is close behind as the kids press on. But he is not the worst of their problems. This time Adam will clash with a terrible enemy who adopts the persona of an evil Aztec god, Tezcatlipoca, and is keen to revive the ancient tradition of human sacrifice. Adam, Justin, and Tukum must play a dreadful ball game of life and death and maybe survive. Will they emerge alive from the jungle? Will Dr. Khalid find the third Stone of Power before they do? Join these young heroes on an adventure steeped in the mythology and legends of the ancient Aztec and Maya!
