The Right Hand of the Sun — Anita Mason

'This is the fifth world.' The emperor opens his fingers. The feather drifts to the floor. 'Every day we are afraid that it will end.' 1519. Shipwrecked on an unnamed coast a Spaniard, who in ten years has learned to live like the natives and worship their gods, is suddenly faced with a choice. Mysterious ships have come. A message is brought to him. Does he want to -- can he -- go back to the world he left? Geronimo has no idea, yet, what purpose is forming in the mind of the expedition's commander. Hernan Cortes will stop at nothing to achieve his ambitions and thwart his enemies -- and he has heard rumours of an empire of gold.
