British writer Sophie Kinsella has died at 55 after a private two-year battle with aggressive brain cancer, her family announced.
Sophie, whose real name was Madeleine Wickham, was one of the world’s most successful romance novelists, with her warm and witty stories leading to over 45 million book sales across 60 countries.
How did Sophie Kinsella die?
In April 2024, she revealed she had been diagnosed with glioblastoma, a fast-progressing brain tumour.
Despite undergoing neurosurgery, the beloved author passed away in her home in Dorset on December 10, 2025.

What is Sophie Kinsella’s legacy?
Madeleine was best known for the “Shopaholic” series starring Becky Bloomwood, a financial journalist with a severe shopping problem. The series began in 2000 with the publication of The Secret Dreamworld of a Shopaholic, which was released internationally as Confessions of a Shopaholic.
The book kicked off a ten-novel saga that would later be adapted into a 2009 film starring Isla Fisher and Hugh Dancy.
Prior to her adoption of the pen name Sophie Kinsella, she published seven ensemble-drama novels under her real name Madeleine Wickham in the mid-1990s.
Starting with The Tennis Party, she told The Guardian that she felt she needed to veer away from a more autobiographical style of writing. “I was so, so determined not to write about a 24-year-old journalist,” she said. “It was going to have male characters, and middle-aged people, so I could say, look, I’m not just writing about my life, I’m a real author.”

What other books did Sophie Kinsella write?
Madeleine described her earlier work as “more serious”, saying they’re “a bit darker and are all ensemble pieces without a main heroine, but groups of characters whose lives interlink in some way.”
She also published stand-alone novels under her pen name such as Can You Keep a Secret?, The Undomestic Goddess and Remember Me?
These books were often described as “chick lit” due to their focus on romantic-comedy-esque situations and women protagonists. “You can be highly intelligent, and also ditzy and klutzy,” she said in defence of the term. “You can be unable to cook, you can like lipstick. And I think it’s more realistic to represent women having all these facets.”
Between 2015 and 2020, Madeleine also created the children’s book series Mummy Fairy and Me, as well as a young adult novel, Finding Audrey, about a teenage girl with social anxiety.
Did Sophie Kinsella have kids?
Sophie and her husband Henry Wickham, whom she married in 1991, had five children together- four sons and one daughter.
