Tenochtitlan, 1519. Strange, pale-skinned people have arrived on the coast of the One World. They hail from a far away land called Spain and fight for the mysterious Hernando Cortš. To confront Cortš' army would be dangerous, but inaction may be even more dangerous.The Mexica are the most powerful people in all the One World and regard the uncouth interlopers with a mixture of curiosity and distrust. Keen to discover their intentions, the Mexica send an official envoy to the coast. What they learn is most troubling. The Spanish possess weapons that have no equal... and they may have designs on Tenochtitlan. The conflict that follows will tear an entire region asunder and give birth to an empire of globe-spanning proportions. Combining the rich world-building of Sharon Kay Penman with the gripping battles sequences of Conn Iggulden, this award-winning novel draws upon modern scholarship to recount an event still unique today: the epic collision of two civilizations separated for millennia.
