Wales' Children's Commissioner Rocio Cifuentes welcomed the move and said having to discuss the book in class had been "psychologically and emotionally" harmful for some black children.

"I was the only black person there in a class which was completely white," said Bowen, who found hearing the racist language in the book repeated in lessons "really awkward" and "confusing".

They did not repeat the N-word while discussing the book in their classroom, she said.

The book starts by giving Green, who navigated mental health challenges after leaving Fleetwood Mac, his due as the band’s founder.

And, fittingly, the book ends with a chapter on Christine, summarizing her life and accomplishments — and ending by noting her jubilant appearance at a 2020 Peter Green tribute concert.
