Cover Stories: Tina Brown on Princess Di; Ratzinger memoirs; Guides to the Lake District

Tina Brown, the former self-styled Queen of New York, is to set aside her book on high-fliers who fall from grace not because it's too close to home, but because she has turned her attention to the legacy of Diana, Princess of Wales. Ed Victor, über-agent, is handling the book, and the assumption is that it will be bought by Caroline Michel at Harper Collins, who had signed off on Brown's previous project, The Icarus Complex. The book will be out in 2007, for the 10th anniversary of Diana's death, and will examine the effect of "her ghost" on monarchy, press and public. Brown was, it is claimed, the first journalist to break the story of difficulties in the Waleses' marriage.

Need a quick shot of Benedictine spirit, guaranteed to kill off all known heresies? The Catholic publisher Ignatius Press has the Ratzinger memoirs up to 1977, Milestones, his Introduction to Christianity and a book-length interview with Peter Seewald, God and the World. Continuum's Cardinal Ratzinger, by John L Allen, tells The Enforcer's tale to 2000. And The End of Time? (Columba) shows him in dialogue with opposing theologians. There'll be no such "relativistic" nonsense now.

This spring, Frances Lincoln goes live with an audacious project: updating the guides to the Lake District by Alfred Wainwright, the Blackburn boy who fell for the Fells at 23, moved there 10 years later, and remained till his death at 84. The series was bought from Michael Joseph two years ago - it couldn't have been worse if Penguin had sold the crown jewels - and the reissue marks its 50th anniversary. Frances Lincoln has employed a former Ordnance Survey staffer to walk the routes, revising the text. The handwriting has been digitised, which means corrections will appear as if in Wainwright's hand. The seven primary guides, written in the 1950s and 1960s, will be published at six-monthly intervals.
