What We Know
Madeleine Sophie Wickham, known to millions as Sophie Kinsella, was diagnosed with glioblastoma in late 2022.

She died surrounded by love and music, according to those close to her.
She is survived by her husband, Henry Wickham, and their five children. Kinsella’s family shares deep gratitude for the care she received, and for the readers who lifted her spirits for more than two decades.

- Date of death: December 10, 2025
Sophie Kinsella’s cause of death is glioblastoma, a fast growing brain cancer. She lived with the diagnosis for three years.
The Voice That Made Us Laugh, Then Feel
Kinsella built a universe with Becky Bloomwood, the lovable lead of the Shopaholic books. Those novels sold tens of millions and helped define modern romantic comedy in print. In 2009, Shopaholic hit the big screen with Isla Fisher, who turned Becky’s optimism and chaos into a pop culture moment.
Her sentences sparkled, but they also saw us. She wrote about money, love, friendship, and shame, then turned them into joy. Readers grew up with her, from Can You Keep a Secret? to I’ve Got Your Number, to standalone gems that became comfort reads on hard days.
Even as she was in treatment, she kept creating. The Burnout arrived in 2023, warm and witty. In 2024, she shared a personal novella that reflected her experience, letting readers into a new chapter of honesty and heart.
A Private Battle, A Public Kindness
Glioblastoma is brutal. Treatments exist, but the road is tough. Kinsella chose privacy first, then openness when she felt ready. That choice gave her family space. It also gave readers a rare kind of hope, the kind that lives in truth.
Her last works took on deeper shades, but her signature light never dimmed. She wrote to make people feel better about themselves. That legacy is not small. It is the reason her books sit on nightstands and in carry-ons around the world.

What Her Loss Means
A bright light has gone out in contemporary romantic comedy fiction. Kinsella gave us a blueprint for funny, kind storytelling that still felt real. You could laugh, then cry, in the very next paragraph. Her influence is stamped on the next generation of authors who blend humor with heart.
There are still chapters left to unfold. Film and TV will continue to rediscover her worlds. New readers will meet Becky for the first time. And longtime fans will keep returning to the pages that taught them how to cheer for themselves.
