Explores the last twenty years in the lives of Princes William and Harry and the evolution of their relationship as adults, with one brother the designated heir, and the other doomed to life as the spare. "Diana's Boys" revealed the iron-strong bond between the teenaged princes, and how it strengthened even more 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 again. Andersen picks up where he left off, covering everything that has happened to the brothers as they have grown up, gotten married to two remarkable women, and had children -- all while facing continual waves of controversy and questions about the ways their relationship has shifted.
