What is the author's tone in The Broken Spears 2007 Revised Edition: The Aztec Account of the Conquest of Mexico by Miguel Leon-Portilla?

The tone is historical, informative, and violent. Although this book is written from old, scholarly literature, efforts have been made to make it palatable for the average reader. In the translator's note, it's written that small liberties were taken with the original text. The thought behind this decision was that the drama of the stories was more important than "stylistic peculiarities." Due to this, words and brief phrases were added or omitted for the sake of clarity.
