The alteration - Kingsley Amis

Hubert Anvil is a 10 year old boy blessed with the voice of an angel.
The Church hierarchy decrees that Hubert should be turned into a castrato - an alteration that could bring Hubert fame and fortune, but would also cut him off from an adult world he is curious to discover.
In a dystopian world where Martin Luther never reformed and where the Holy Office's power is absolute, where will Hubert turn if he decides to defy their wishes?

Kingsley Amis was born in south London in 1922 and was educated at the City of London School and St John's College, Oxford. After the publication of Lucky Jim in 1954, Kingsley Amis wrote over twenty novels, including The Alteration, winner of the John W. Campbell Memorial Award, The Old Devils, winner of the Booker Prize in 1986, and The Biographer's Moustache, which was to be his last book. He also wrote on politics, education, language, films, television, restaurants and drink.
Kingsley Amis was awarded the CBE in 1981 and received a knighthood in 1990. He died in October 1995.

The disorientating world of The Alteration is the same but different, familiar yet strange
