Return of the plumed serpent - Graham Hancock

Graham Hancock, an expert in ancient civilisations and author of the 7 million selling Fingerprints of the Gods, and expert too, on the use of hallucinogens to achieve higher states of consciousness, brings these two interests together in the second volume of the War God trilogy.

The conquistador Hernn Corts is dreaming of Tenochtitlan, the golden city of Aztecs. But in order to win the Aztecs' gold, Corts and his small force of just five hundred men will have to defeat the psychotic emperor Moctezuma and the armies of hundreds of thousands he commands.

Corts expects that the warlike Tlascalans, hereditary enemies of the Aztecs, will join him, but instead finds himself locked in a deadly struggle. Even as Corts risks all in the bloody campaign against the Tlascalans, he plays mind games with Moctezuma, aiming to dismantle the Aztec emperor's confidence and defeat him psychologically before ever having to face him on the battlefield.

In this he is aided by his lover Malinal, a beautiful Mayan princess. It is from Malinal that Corts learns of the myth of Quetzalcoatl, 'The Plumed Serpent'. She shows him how to exploit the prophecy of the fabled god king's return to weaken Moctezuma's resolve and keep alive the suspicion that the conquistador might actually be Quetzalcoatl himself.

Meanwhile Malinal's friend, the witch Tozi, wages a supernatural war of her own against Hummingbird, the terrifying demon the Aztecs worship as a god, and against the evil sorcerer Acopol who does his bidding.
