Until surprisingly recently, most history books noted that America was discovered in 1492 by Christopher Columbus. The truth was that by the time that Columbus arrived in America, people had been living there for more than 12,000 years. This is the story of the gradual rise, sudden destruction, and slow recovery of the native people of North America.

Beginning with the birth of the nation, slavery divided and caused conflict for the United States of America, worsening during the country's early decades as the practice became more economically vital. Finally, in 1861, the American Civil War erupted after the election of President Abraham Lincoln. Never acknowledging the South’s right to secede, Lincoln and the North fought the South through four long, bloody, destructive years; much longer than anyone thought the war would last.

What do you think of when you consider the Middle Ages? Knights in armor and damsels in distress? Vikings plundering monasteries? Religious dissenters burning at the stake? The dead bodies piling up as war, famine, and plague devastated Europe? Think again. While all these are part of the tapestry of the medieval era, the threads of politics, personality and war, culture, religion, education and the arts are vastly more intricate and fascinating.

On a battlefield so littered with dead bodies that General Ulysses S. Grant said it would have been possible to walk across it in any direction without a foot touching the ground, the Union Army notched a brutal but significant victory against the Confederate Army. The two-day battle, with the highest number of casualties recorded in the fighting up to that time, dashed the hopes of a short war. Still, few could have grasped that this battle was only the beginning of a national campaign of slaughter that would see so many Yankee and Rebel deaths.

Messages written in secret codes or invisible ink, agents operating behind enemy lines and known only by code names, the provision of vital secret intelligence used to direct military operations—these are staple elements of modern spy fiction. Still, all were used more than 200 years ago by one of the first professional spy networks ever created: the Culper Spy Ring. This is the story of a network of courageous patriot spies operating for several years in British-occupied New York during the American Revolutionary War.
