The Castle of Kukulcan: The Serpent Passage Series Book 3

The battle to protect Earth beyond the end of the Great Cycle of 2012 doesn't happen now, with our modern weapons and technology, but rather takes place a thousand years ago, in the times of the ancient Maya. William and his friends must overcome dangerous and bizarre challenges to rescue the Mayans who were abducted by the Grey Ones, and reach Chich n Itz to finish building the Castle of Kukulcan, and create a new Tree of Life. To succeed in their mission, they have to stop a damaging storm curse, while overcoming an invading army of Toltecs led by an evil shapeshifting feathered serpent. Fortunately, there are those who side with William and the Maya; a team of Toltecs led by Quetzalcoatl-the Maya call him Kukulcan. Although the Maya are greatly outnumbered, the bloodstone has become stronger than ever, and William needs to use his powers wisely in their final stand to save the world from the Mayan Apocalypse.
