Michelle Sagara writes as Michelle Sagara, Michelle West, and has been published as Michelle Sagara West. She lives in Toronto with her family and Way Too Many Books. She does read ebooks, but started reading when ebooks didn’t exist, and can’t quite bear to part with the physical books, which she has been known to weep over, throw, or clutch tightly like a gleeful, maniacal fiend. When she was six, she believed that every book in existence was written and drawn by hand, and she was very, very frustrated that her attempts to write a book never looked as perfect as the books she loved, no matter how much she practiced writing the letters. Oddly enough, as a writer she has learned that it is impossible to write the perfect book, but she keeps trying.

This is the true story of C.S. Lewis – one of the greatest writers of the 20th-century – whose books for children and adults have become much loved classics. Part of the story of C.S. Lewis has been made famous through the film ‘Shadowlands’. Here this fascinating man’s entire life story is told by those who knew him personally. C.S. Lewis was born in Belfast in 1898 and was sent to England for a public school education with his elder brother, Warren. Lewis exhibited a genius for imagination and perception from his earliest years. Brought up in a Christian household, Lewis lost his faith in his teenage years but was to regain it, with reluctance, as a fellow at Magdalen College, Oxford. His faith subsequently influenced his writings. He became a vigorous champion of the Christian faith through classics such as ‘Mere Christianity’ and through his BBC broadcasts. His ‘Chronicles of Narnia’ became children’s classics and he was deluged with correspondence from his young readers. In his latter years he unexpectedly fell deeply in love with a divorced American, Joy Greshem, and married her, only to suffer the devastation of her death a few years later. C.S. Lewis died in 1963 at his home in Oxford. During his lifetime C.S. Lewis suggested to his friend, Roger Lancelyn Green, who was a fellow English scholar, that he would undertake his biography one day. After Lewis’s death in 1963 Lancelyn Green and Walter Hooper were approached by several of Lewis’s friends to write the biography. Warren Lewis, brother to Jack, contributed a great deal to the writing. The authors had at their disposal a vast collection of letters and diaries, as well as the recollections of many surviving family members and friends. Walter Hooper has enhanced the original text with additional material to provide a new, expanded edition which all C.S. Lewis fans will be keen to own.

At the age of only 36, Sir Mark Sykes was signatory to the Sykes-Picot agreement, one of the most reviled treaties of modern times. A century later, Christopher Sykes’ lively biography of his grandfather reassesses his life and work, and the political instability and violence in the Middle East attributed to it. The Sykes–Picot agreement was drawn by the eponymous British and French diplomats in 1916 to determine the divide of the collapsing empire in the event of an allied victory in World War I. Excluding Arab involvement, it negated their earlier guarantee of independence made by the British – and controversy has raged around it ever since. But who was Mark Sykes? A century on, Christopher Simon Sykes reveals new facets of a misremembered diplomatic giant. Using previously undisclosed family letters and cartoons by his grandfather, he delivers a comprehensive and humbling account of the man behind one of the most impactful policies in the Middle East.
