Inside the Private Lives of William, Kate, Harry and Meghan

Christopher Andersen’s bestselling book, Diana’s Boys, revealed the powerful bond between the teenaged princes, and how it strengthened in the wake of their mother’s tragic death. Now, twenty years later, Queen Elizabeth II is in her mid-nineties, Prince Charles is in his seventies, and all eyes are turned increasingly toward William and Harry. In BROTHERS AND WIVES: Inside the Private Lives of William, Kate, Harry, and Meghan (Gallery Books; Hardcover; on-sale November 30), Andersen picks up where he left off, covering everything that has happened to the brothers as they have grown up, gotten married and had children—all while facing continual waves of controversy and questions about the ways their relationship has shifted.
