The book, published in 2017, is a commentary on the experience of young black-Americans, focusing on a 16-year old-girl as she navigates life between her poor neighbourhood and white, affluent classmates at school.
Debuting at number one on the New York Times’ young adult best-seller list, it describes police brutality and racial bias, as one of her best friends is shot by a white police officer.
In the year it was published, it was one of the top ten most-challenged books in the US by schools and libraries who listed profanity, drug use, and sexual references as a reason to ban it, according to the American Library Association.
Speaking to BBC Radio Solent’s Dorset Breakfast show, Mr Farquharson said the school held sessions where pupils would read aloud to the class.
He said: “I’m sure a 14-year-old girl or boy should not be expected to stand in front of their peers and read out some of the stuff you can find in this book.
“They shouldn’t be normalising the sorts of sexual activity that’s happening – and the language – to kids in their class.”
Mr Farquharson said the book depicted white people “as the baddies”, adding: “The concern I have is they are not balancing that out… and they might come away with an understanding that they are inherently baddies.”
A school spokesperson said: “We acknowledge that the novel raises important themes and is promoted as appropriate for readers that are aged 14-plus, however, after careful consideration, we have decided that there are alternative texts that raise similar themes which are better suited to our students in Year 10.”
