LONDON, UK – British author Sophie Kinsella, best known for her bubbly rom-com series “Confessions of a Shopaholic,” has died at the age of 55 after a battle with brain cancer. Her family announced on Kinsella’s Instagram account that she passed away peacefully, surrounded by her loved ones, saying her final days were filled with music, family, warmth, and joy.

Kinsella, who also published under her real name, Madeleine Wickham, revealed in April 2024 that she had been diagnosed with glioblastoma, an aggressive form of brain cancer, more than a year earlier. She had kept the diagnosis private initially to allow her children to process the news in privacy. Kinsella rose to worldwide fame with the “Shopaholic” series, beginning with “The Secret Dreamworld of a Shopaholic” in 2000, which introduced readers to the debt-prone Becky Bloomwood. Over her career, she sold more than 45 million books, which were translated into dozens of languages, and several of her novels were adapted into films, including the 2009 movie “Confessions of a Shopaholic.”

Kinsella’s early life in London included music and composition, and she initially studied music at Oxford before switching to politics, philosophy, and economics. She worked as a financial journalist, where her daily commutes inspired her first novel, “The Tennis Party,” published in 1995. Her breakthrough came with the “Shopaholic” series, written under the pen name Sophie Kinsella to distinguish it from her previous works. Kinsella created a character who humorously navigated debt, shopping, and romance, and the series became a defining example of modern “chick lit,” a label she embraced as stories of contemporary heroines with humor and heart.

Beyond the “Shopaholic” novels, Kinsella wrote other bestselling works, including “The Undomestic Goddess,” “Remember Me?,” “Twenties Girl,” and young adult and children’s books such as “Finding Audrey” and “My Mummy Fairy and Me.” Her last novel, “The Burnout,” was published in 2023. During her illness, she continued writing, creating a novella, “What Does It Feel Like,” about a woman navigating brain cancer while raising five children, reflecting her hope and optimism even in her final months.
