Two iconic dynasties—the Kennedys and the Windsors—whose glamour and ambition defined an era.

** For fans of FX’s new Ryan Murphy limited series Love Story. **

For nearly a century, two families an ocean apart have captured the world’s collective imagination: the British Windsors and the American Kennedys. Much ink has been spilled on their individual trysts, tragedies, and triumphs over the years, but no one has examined their powerful and intertwined legacies. Until now.

In The Kennedys and the Windsors, acclaimed journalist Caroline Hallemann unearths the story of two iconic families whose lives, ambitions, and respective reigns have mirrored each other in surprising ways. Through rich archival research and fresh interviews from insiders on both sides of the Atlantic, Hallemann reveals how an upstart Irish Catholic family with little access into elite New England society came to host dinner parties for a King and Queen, and forge an eventual path to the White House. In the process, she draws out some startling parallels between the two families: the style icons Princess Diana and Carolyn Bessette-Kennedy (both tragically gone too soon), the frustrated “second sisters” Princess Margaret and Lee Radziwill, the scandal-plagued next generation of Robert F. Kennedy Jr. and the man formerly known as Prince Andrew, and the current generation’s shared struggle to figure out what a monarchy (actual or imagined) means in the twenty-first century.

From Queen Elizabeth’s coronation to President Kennedy’s historic London visit, from JFK Jr.’s shocking death to Prince Harry’s decisive break with his family, Hallemann traces the key moments in the lives of these two dynasties through a fresh and fascinating lens, showing how they have intersected over the generations in ways that not only shaped their images and legacies, but history itself.
