Former presidents have an unusual place in American life. King George III believed that George Washington’s departure after two terms made him “the greatest character of the age.” But Alexander Hamilton worried former presidents might “[wander] among the people like ghosts.” They were both right. Life After Power tells the stories of seven former presidents, from the Founding to today. Each changed history. Each offered lessons about how to decide what to do in the next chapter of life.

From 1783, when German immigrant John Jacob Astor first arrived in the United States, until 2009, when Brooke Astor’s son, Anthony Marshall, was convicted of defrauding his elderly mother, the Astor name occupied a unique place in American society. The family fortune, first made by a beaver trapping business that grew into an empire, was then amplified by holdings in Manhattan real estate. Over the ensuing generations, Astors ruled Gilded Age New York society and inserted themselves into political and cultural life, but also suffered the most famous loss on the Titanic.

To look south and skyward from Central Park these days is to gaze upon a physical manifestation of tens of billions of dollars in global wealth: a series of soaring spires stretching from Park Avenue to Broadway. Known as Billionaires’ Row, this set of slender high-rise residences has transformed the skyline of New York City, thanks to developer-friendly policies and a seemingly endless gush of cash from tech, finance, and foreign oligarchs. And chances are most of us will never be invited to step inside.

Perceptive, funny, and nostalgic, E. B. White's stroll around Manhattan remains the quintessential love letter to the city, written by one of America's foremost literary figures. The New York Times named Here Is New York one of the 10 best books ever written about the metropolis, and The New Yorker called it "the wittiest essay, and one of the most perceptive, ever done on the city".

Before 1862, Joshua Lawrence Chamberlain had rarely left his home state of Maine, where he was a trained minister and mild-mannered professor at Bowdoin College. His colleagues were shocked when he volunteered for the Union army, but he was undeterred and later became known as one of the North’s greatest heroes: On the second day at Gettysburg, after running out of ammunition at Little Round Top, he ordered his men to wield their bayonets in a desperate charge down a rocky slope that routed the Confederate attackers.
