Fifth Sun offers a comprehensive history of the Aztecs, spanning the period before conquest to a century after the conquest, based on rarely-used Nahuatl-language sources written by the indigenous people. This is the best book on the Aztecs yet written, full stop... The value of Fifth Sun lies in how it rescues Aztecs and Nahuas from centuries of colonialist caricature and renders them human again - fully human, with flaws, people capable of brutal violence but also of deep love.
