In the spring of 1519, Hernán Cortés arrived at the shores of Mexico to conquer the Aztec Empire and claim its gold for the glory of Spain. Aiding his effort was one of the greatest coincidences in history-the Aztec belief that, at the exact moment of Cortés' arrival, their civilization was to be visited by Quetzalcoatl, the light-skinned and plumed Aztec god of wisdom.
Mistaking Cortés for Quetzalcoatl was a fatal, civilization-crushing error.
That's what the history books tell us.
But sometimes, right in the middle of the history we know, somebody goes and does something to change one important detail, and the world is never the same...
In 1999, unremarkable Spanish bureaucrat Dave Aragon finds himself on the gritty back streets of the Aztec capital of Tenochtitlan, investigating a grisly ritualistic murder that threatens to derail the fragile diplomatic relationship between his Spanish colonial government and the Pan-Aztecan Empire.
Dave enlists the help of T'shla, a former lover and Aztecan IT wiz, who was saved from human sacrifice as a young girl. Together, Dave and T'shla must outsmart corrupt high priests, evade deadly Jaguar agents, and challenge the living god Quetzalcoatl as they unwittingly uncover secrets that promise to disrupt the very nature of their universe.
