Essential Background

Born Madeleine Sophie Wickham, Sophie Kinsella was a widely beloved author whose novels sold over 50 million copies worldwide and were translated into more than 40 languages. She was most famous for her "Shopaholic" series, which began with "The Secret Dreamworld of a Shopaholic" (published as "Confessions of a Shopaholic" in the US) in 2000, and was later adapted into a popular film. In late 2022, Kinsella was diagnosed with glioblastoma, a severe form of brain cancer, but she kept the diagnosis private for over a year to allow her children to adjust to their "new normal" before publicly announcing it in April 2024. She received treatment, including surgery, radiotherapy, and chemotherapy, at University College Hospital in London.

Kinsella had openly discussed her illness since revealing it in April 2024, and her last novel, "What Does It Feel Like?", published in 2024, was a semi-autobiographical account inspired by her experience with brain cancer and recovery from surgery.
