This ninth book in the Killing history series by conservative pundit Bill O'Reilly provides a vivid account of America's westward expansion and the Indian Wars of the 19th century.

The founding of the United States of America is often presented as a heroic tale of underdogs securing their independence from a global empire.

But what happens when a fledgling nation is founded on territory where people have already lived for centuries?

Best known as a conservative political commentator who spent over two decades at Fox News as the host of The O'Reilly Factor, Bill O'Reilly is also a student of American history.

Working with his co-author, former sports journalist Martin Dugard, O'Reilly's has used each book in his series to explore a pivotal historical death and the context surrounding it.

This ninth installment in the Killing series covers the intense Indian Wars of the 19th century, with the death of the iconic chief Crazy Horse as its symbolic focal point.

With a cast of such complex characters as Native American leaders Cochise, Sitting Bull, and Geronimo alongside U.S. generals Andrew Jackson, William Sherman, and the flamboyant George Custer, Killing Crazy Horse blends well-researched historical context with a humanizing narrative.
