WINNER OF THE SOUTH BANK SKY ARTS LITERATURE AWARD 2018 A GUARDIAN BOOK OF THE YEAR ? A TIMES BOOK OF THE YEAR ? A SUNDAY TIMES BOOK OF THE YEAR ? A DAILY MAIL BOOK OF THE YEAR ‘A masterpiece’ Mail on Sunday ‘I honked so loudly the man sitting next to me dropped his sandwich’ Observer She made John Lennon blush and Marlon Brando clam up. She cold-shouldered Princess Diana and humiliated Elizabeth Taylor. Andy Warhol photographed her. Jack Nicholson offered her cocaine. Gore Vidal revered her. John Fowles hoped to keep her as his sex-slave. Dudley Moore propositioned her. Francis Bacon heckled her. Peter Sellers was in love with her. For Pablo Picasso, she was the object of sexual fantasy. “If they knew what I had done in my dreams with your royal ladies” he confided to a friend, “they would take me to the Tower of London and chop off my head!” Princess Margaret aroused passion and indignation in equal measures. To her friends, she was witty and regal. To her enemies, she was rude and demanding. In her 1950’s heyday, she was seen as one of the most glamorous and desirable women in the world. By the time of her death, she had come to personify disappointment. One friend said he had never known an unhappier woman. The tale of Princess Margaret is pantomime as tragedy, and tragedy as pantomime. It is Cinderella in reverse: hope dashed, happiness mislaid, life mishandled. Combining interviews, parodies, dreams, parallel lives, diaries, announcements, lists, catalogues and essays, Ma’am Darling is a kaleidoscopic experiment in biography, and a witty meditation on fame and art, snobbery and deference, bohemia and high society. ‘Brown has been our best parodist and satirist for decades now … Ma’am Darling is, as you would expect, very funny; also, full of quirky facts and genial footnotes. Brown has managed to ingest huge numbers of royal books and documents without losing either his judgment or his sanity. He adores the spectacle of human vanity’ Julian Barnes, Guardian

A tense and layered true-crime story about an all-American soldier boy turned bank robber Alex Blum was a clean-cut all-American kid with one unshakeable goal in life: to serve his country in the military. He was accepted into the elite Rangers regiment, but on the first day of his leave before deployment to Iraq, Alex got into his car with two fellow soldiers and two strangers, drove to a local bank in Tacoma, and committed armed robbery. The Blum family was devastated and mystified. How could he have done such a thing? Alex’s attorney presented a defence based on the theory that trainee Rangers are indoctrinated on a level akin to the brainwashing in an extreme religious cult, and Alex insisted that he had believed the robbery was just another exercise in the famously daunting Ranger program. But Luke Elliot Sommer, the charismatic soldier behind the robbery, maintained that Alex knew exactly what he was doing, and had, in fact, planned it all with him. Who was lying? What had happened to Alex during those gruelling months of training? How accountable was he?

Imagine a sisterhood – across all creeds and cultures. An unspoken agreement that we, as women, will support and encourage one another. That we will remember we don't know what struggles each of us may be facing elsewhere in our lives and so we will assume that each of us is doing our best… So begins WE: an inspiring, empowering and provocative manifesto for change. Change which we can all effect, one woman at a time. Change which provides a crucial and timely antidote to the 'have-it-all' Superwoman culture and instead focusses on what will make each and every one of us happier and more free. Change which provides an answer to the nagging sense of 'is that it?' that almost all of us can succumb to when we wake in the dead of night. Written by actress Gillian Anderson and journalist Jennifer Nadel – two friends who for the last decade have stumbled along together, learning, failing, crying, laughing and trying again – WE is a not a theoretical treatise but instead a rallying cry to create a life that has greater meaning and purpose. Combining tools which are practical, psychological and spiritual, it is both a process and a vision for a more fulfilling way of living. And a truly inspiring vision of a happier, more emotionally rewarding future we can all create together…

The only authorised biography, and the only one written by an author who actually met J.R.R. Tolkien, with a redesigned cover to match the distinctive paperback editions of The Lord of the Rings, The Silmarillion and Unfinished Tales. In the 25 years since Tolkien's death in September 1973, millions have read The Hobbit, The Lord of the Rings and The Silmarillion and become fascinated about the very private man behind the books. Born in Bloemfontein in January 1892, John Ronald Reuel Tolkien was orphaned in childhood, brought up in near-poverty and almost thwarted in adolescent romance. He served in the First World War, surviving the Battle of the Somme, where he lost some of his closest friends, and returned to academic life, achieving high repute as a scholar and university teacher, eventually becoming Merton Professor of English at Oxford. Then suddenly his life changed dramatically. One day while marking essay papers he found himself writing 'In a hole in the ground there lived a hobbit' -- and worldwide renown awaited him. Humphrey Carpenter was given unrestricted access to all Tolkien's papers, and interviewed his friends and family. From these sources he follows the long and painful process of creation that produced The Lord of the Rings and The Silmarillion and offers a wealth of information about the life and work of the twentieth century's most cherished author.
