More than a century ago, the new Bolshevik government began sending Soviet citizens abroad as deep-cover spies, training them to pose as foreign aristocrats, merchants, and students. Over time, this grew into the most ambitious espionage program in history. Many intelligence agencies use undercover operatives, but the KGB was the only one to go to such lengths, spending years training its spies in language and etiquette, and sending them abroad on missions that could last for decades. These spies were known as “illegals.”

The Mexican War brought vast new territories to the United States, which precipitated a growing crisis over slavery. The new territories seemed unsuitable for the type of agriculture that depended on slave labor, but they lay south of the line where slavery was permitted by the 1820 Missouri Compromise. The subject of expanding slavery to the new territories became a flash point between North and South.

At the start of the 1860 presidential campaign, a handful of fired-up young Northerners appeared as bodyguards to defend anti-slavery stump speakers from frequent attacks. The group called themselves the Wide Awakes. Soon, hundreds of thousands of young White and Black men, and a number of women, were organizing boisterous, uniformed, torch-bearing brigades of their own. These Wide Awakes--mostly working-class Americans in their twenties--became one of the largest, most spectacular, and most influential political movements in our history.

December 1944. Soviet and German troops fight from house to house in the shattered, corpse-strewn suburbs of Budapest. Crazed Hungarian fascists join with die-hard Nazis to slaughter Jews day and night, turning the Danube blood-red. In less than six months, thirty-eight-year-old SS Colonel Adolf Eichmann has sent over half a million Hungarians to the gas chambers in Auschwitz. Now all that prevents him from liquidating Europe's last Jewish ghetto is an unarmed Swedish diplomatic envoy named Raoul Wallenberg.

The American Civil War stands at the center of the story, its military history and the drama of emancipation the highlights. Taylor relies on vivid characters to carry the story, from Joseph Hooker, whose timidity in crisis was exploited by Robert E. Lee and Stonewall Jackson in the Union defeat at Chancellorsville, to Martin Delany and Mary Ann Shadd Cary, Black abolitionists whose critical work in Canada and the United States advanced emancipation and the enrollment of Black soldiers in Union armies.
