Kingsley Amis’ 1976 The Alterationis a stand-alone alternate history novel.
King Stephen III of England, is dead! Long live King William V, whose reign begins in the Year of Our Lord 1976. Gathered for Steven III’s funeral: many of Europe’s most prestigious figures. It will be a grand occasion.
Young Hubert Anvil is to sing at the funeral. This is a great honour, but it leads to a demand that he does not want to accept but doesn’t see how to refuse.
