Prophecies that the dollar will lose its status as the world's dominant currency have echoed for decades—and are increasing in volume. Cryptocurrency enthusiasts claim that Bitcoin or other blockchain-based monetary units will replace the dollar. Foreign policy hawks warn that China's renminbi poses a lethal threat to the greenback. And sound money zealots predict that mounting US debt and inflation will surely erode the dollar's value to the point of irrelevancy.

In October 2008, someone going by the name Satoshi Nakamoto posted a white paper outlining “a peer-to-peer electronic cash system” called Bitcoin to an arcane listserv populated by Cypherpunks. No one in the community had heard of Nakamoto, and just as people were starting to wonder who he was, he vanished. As the years passed, and the scope of Nakamoto’s achievement became clear, the truth of his identity grew into the greatest unsolved mystery of our time.

For listeners of Walter Isaacson’s Steve Jobs and Chris Miller’s Chip War, a riveting look at how Apple helped build China’s dominance in electronics assembly and manufacturing only to find itself trapped in a relationship with an authoritarian state making ever-increasing demands.

We set out on the James River, March 25, 1865, aboard the paddle steamboat River Queen. President Lincoln is on his way to General Grant’s headquarters at City Point, Virginia, and he’s decided he won’t return to Washington until he’s witnessed, or perhaps even orchestrated, the end of the Civil War.

By any measure, Julius Caesar is one of the most significant and well-known figures in ancient Roman history. Self-identified as a "popular" politician, he advocated for effective government to better the lives of the average Roman; however, he believed this government could not be based upon the existing democracy, which he regarded as corrupt and inefficient. It could only be through his personal management and the massive organization he built to overthrow the government that he could ensure the prosperity of all Romans.

As a tough but smart Italian American kid, Ernest Cuneo played Ivy League football at Columbia University and was in the old Brooklyn Dodgers NFL franchise before becoming a city hall lawyer and “Brain Trust'' aide to President Roosevelt. He was on the payroll of national radio columnist Walter Winchell and mingled with the famous and powerful. But his status as a spy remained a secret, hiding in plain sight. During this time, Cuneo began a close friendship with British spy Ian Fleming and helped inspire Fleming's James Bond novels.

At the dawn of the twentieth century, José Cuervo inherited his family's humble distillery, La Rojeña, in the Tequila Valley. Within a decade, it would become Mexico's leading producer of tequila. But when the Mexican Revolution erupted, a charge of treason and a death threat against him by Pancho Villa forced Cuervo to flee. In Tequila Wars, award-winning author Ted Genoways restores Cuervo to his place as a key player in Mexico's formative period. Before the revolution, Cuervo's acclaim spread worldwide, and once war broke out, Cuervo remained an impresario, kingmaker, and cultural force.
