Book excerpt: "One of the masterpieces of British political history” (The New York Times) boasts unprecedented access to Thatcher colleagues, friends, family, and all her government and private papers, and offers a groudbreaking and essential portrait of a titanic figure, with all her capabilities and flaw, during the years of her greatest power. In June 1983 Margaret Thatcher won the biggest increase in a government’s parliamentary majority in British electoral history and proceeded to transform relations with Europe, prioritize British industry, and reinvigorate the economy. For the only time since Churchill, Britain had a central place in dealings between the superpowers. But even at her zenith, Thatcher was best by difficulties. She regularly faced calls for resignation, grew isolated in her own government, butted heads with the Queen, bullied her senior colleagues, and was deceived by her closest ally, Ronald Reagan, during the U.S. invasion of Grenada. Thatcher storms from these pages as from no other book.
