Not For Turning is the first volume of Charles Moore’s authorized biography of Margaret Thatcher, one of the most influential political figures of the postwar era. Moore’s biography of Thatcher, “published after her death on April 8, 2013, immediately supersedes all earlier books written about her,” said a review in goodreads.com. “At the moment when she becomes a historical figure, this book also makes her into a three dimensional one for the first time,” it added. It said the biography “gives unparalleled insight into her early life and formation, especially through her extensive correspondence with her sister, which Moore is the first author to draw on.” The book “recreates brilliantly the atmosphere of British politics as she was making her way, and takes her up to what was arguably the zenith of her power, victory in the Falklands. (This volume ends with the Falklands Dinner in Downing Street in November 1982.)” Moore “does not shy away from criticizing her or identifying weaknesses and mistakes where he feels it is justified,” said the review.
