The Alteration

The Alteration is the title of a 1976 alternate history novel by Kingsley Amis, set in a parallel universe in which the Reformation did not take place. It won the John W. Campbell Memorial Award in 1977.
The year is 1976 and we are alive in an all-Catholic world. The Reformation never took place because Martin Luther made a deal with Rome and became Pope Martin I. The "alteration" proposed to Hubert Anvil, brilliant 10-year-old boy soprano, is that most feared by all males. Pope John XXIV wishes Hubert to preserve the purity of his voice to glorify the Church on a permanent basis; Hubert wishes to share his talent but he has some disquieting thoughts about Pope John's proposal.
