Never again,'' became Queen Elizabeth II's mantra shortly after Diana's death. More specifically, there could never be ''another Diana''-a member of the family whose global popularity upstaged, outshone, and posed an existential threat to the British monarchy.

Picking up where The Diana Chronicles left off, The Palace Papers reveals how the royal family reinvented itself after the traumatic years when Diana's blazing celebrity ripped through the House of Windsor like a comet.

Tina Brown takes readers on a tour de force journey that shows the Queen's stoic resolve as she coped with the passing of Princess Margaret, the Queen Mother, and her partner for seven decades, Prince Philip, and triumphed in her Jubilee years even as the family dramas raged around her. She explores Prince Charles's determination to make Camilla his queen, the tension between two princes on ''different paths,'' the ascendence of the resolute Kate Middleton, the disturbing allegations surrounding Prince Andrew and Jeffrey Epstein, and Harry and Meghan's stunning decision to ''step back'' as senior royals. Despite the fragile monarchy's best efforts, ''never again'' seems fast approaching.

Full of powerful revelations, nuanced details, and searing insight, The Palace Papers will irrevocably change how the world perceives and understands the royal family.
