Mirror Mirror is already available to pre-order on Amazon now, ahead of its release on October 5. The book’s Amazon blurb reveals that the four friends are in a band together until one day Naima ‘dies in tragic circumstances leaving behind only one word: Sorry’.

‘What awful truth was she hiding?’ the blurb continues. ‘What dark secret was lurking behind her seemingly sunny persona? And how did Red, the self-styled protector of the group, fail to spot the warning signs?’.

Speaking to Vogue, the book’s publisher Anna Valentine said the model wanted to write a book that resonated with her audience. “She has an enormous following and is incredibly in touch with her followers,” Valentine said.

“She wanted to write a book that dealt with issues young people face today, and that was the thing that was really exciting for us.” According to the Evening Standard, a second draft of the book is due by the end of this month before its release in October.
