In the summer of 1846, the Army of the West marched through Santa Fe, en route to invade and occupy the Western territories claimed by Mexico. Fueled by the new ideology of “Manifest Destiny,” this land grab would lead to a decades-long battle between the United States and the Navajos, the fiercely resistant rulers of a huge swath of mountainous desert wilderness.

Empire of the Summer Moon spans two astonishing stories. The first traces the rise and fall of the Comanches, the most powerful Indian tribe in American history. The second entails one of the most remarkable narratives ever to come out of the Old West: the epic saga of the pioneer woman Cynthia Ann Parker and her mixed-blood son, Quanah, who became the last and greatest chief of the Comanches.

The great Oglala Sioux chief Red Cloud was the only Plains Indian to defeat the United States Army in a war, forcing the American government to sue for peace in a conflict named for him. At the peak of their chief’s powers, the Sioux could claim control of one-fifth of the contiguous United States. But unlike Sitting Bull, Crazy Horse, or Geronimo, the fog of history has left Red Cloud strangely obscured. Now, thanks to painstaking research by two award-winning authors, his incredible story can finally be told.

In 1541, the brutal conquistador Gonzalo Pizarro and his well-born lieutenant Francisco Orellana set off from Quito in search of La Canela, South America's rumored Land of Cinnamon, and the fabled El Dorado, "the golden man". Driving an enormous retinue of mercenaries, enslaved natives, horses, hunting dogs, and other animals across the Andes, they watched their proud expedition begin to disintegrate even before they descended into the nightmarish jungle, following the course of a powerful river.

The “mountain men” were the hunters and trappers who fiercely strode the Rocky Mountains in the early to mid-1800s. They braved the elements in search of the skins of beavers and other wild animals, to sell or barter for goods. The lifestyle of the mountain men could be harsh, existing as they did among animals, and spending most of their days and nights living and camping out in the great unexplored wilds of the Rockies.
