The completion of the transcontinental railroad in May 1869 is usually told as a story of national triumph and a key moment for American Manifest Destiny. The Railroad made it possible to cross the country in a matter of days instead of months, paved the way for new settlers to come out west, and helped speed America's entry onto the world stage as a modern nation that spanned a full continent. It also created vast wealth for its four owners, including the fortune with which Leland Stanford would found Stanford University some two decades later.

Between 1848 and 1899, more gold was removed from the earth than had been mined in the 3,000 preceding years, bringing untold wealth to individuals and nations. But friction between Chinese and white settlers on the goldfields of California, Australia, and South Africa catalyzed a global battle over "the Chinese Question": Would the United States and the British Empire outlaw Chinese immigration?

When Reyna Grande was nine years old, she walked across the US-Mexico border in search of a home, desperate to be reunited with the parents who had left her behind years before for a better life in the City of Angels. What she found instead was an indifferent mother, an abusive, alcoholic father, and a school system that belittled her heritage. With so few resources at her disposal, Reyna finds refuge in words, and it is her love of reading and writing that propels her to rise above until she achieves the impossible and is accepted to the University of California, Santa Cruz.

The United States and China are locked in a “cold tech war", and the winner will end up dominating the 21st century. America can still catch up. Unfortunately, Americans, focused on other matters, are not meeting the challenges China presents. A whole-of-society mobilization will be necessary for the US to regain what it once had: control of cutting-edge technologies. Americans may not like the fact that they’re once again in a Cold War-type struggle, but they will either adjust to that reality or get left behind.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.
