The contemporary art market is an international juggernaut, throwing off multimillion-dollar deals as wealthy buyers move from fair to fair, auction to auction, party to glittering party. But none of it would happen without the dealers - the tastemakers who back emerging artists and steer them to success, often to see them picked off by a rival. Dealers operate within a private world of handshake agreements, negotiating for the highest commissions. Michael Shnayerson, a longtime contributing editor to Vanity Fair, writes the first-ever definitive history of their activities.

In 1945, the Soviet Union controlled half of Europe and was a founding member of the United Nations. By 1991, it had an army four million strong, 5,000 nuclear-tipped missiles, and was the second biggest producer of oil in the world. But soon afterward, the union sank into an economic crisis and was torn apart by nationalist separatism. Its collapse was one of the seismic shifts of the 20th century.

For Americans, World War II began in December of 1941, with the bombing of Pearl Harbor; but for Poland, the war began on September 1, 1939, when Hitler's soldiers invaded, followed later that month by Stalin's Red Army. The conflict that followed saw the debut of many of the features that would come to define the later war-blitzkrieg, the targeting of civilians, ethnic cleansing, and indiscriminate aerial bombing-yet it is routinely overlooked by historians.

On the night of January 30, 1933, Adolf Hitler leaned out of a spotlit window of the Reich chancellery in Berlin, bursting with joy. The moment seemed unbelievable, even to Hitler. After an improbable political journey that came close to faltering on many occasions, his march to power had finally succeeded. While the path of Hitler's rise has been told in books covering larger portions of his life, no previous work has focused solely on his eight-year climb to rule: 1925-1933.

In the aftermath of World War II, Prussia - a centuries-old state pivotal to Europe's development - ceased to exist. In their eagerness to erase all traces of the Third Reich from the earth, the Allies believed that Prussia, the very embodiment of German militarism, had to be abolished. But as Christopher Clark reveals in this pioneering history, Prussia's legacy is far more complex.

General Chuck Yeager was the greatest test pilot of them all - the first man to fly faster than the speed of sound...the World War II flying ace who shot down a Messerschmitt jet with a prop-driven P-51 Mustang...the hero who defined a certain quality that all hotshot fly-boys of the postwar era aimed to achieve: the right stuff. Now he tells his whole incredible life story with the same “wide-open, full throttle” approach that has marked his astonishing career.
