The world of contemporary fiction has lost one of its brightest stars. Sophie Kinsella, the globally adored author whose witty novels delighted millions, has died at the age of 55 after a fiercely private battle with an aggressive brain tumour. Her estimated personal net worth at the time of her passing was $40 million.
The writer, whose real name was Madeleine Sophie Wickham, passed away peacefully on Wednesday, December 10, 2025. She had been diagnosed with glioblastoma—a particularly deadly form of cancer—approximately three years ago, only revealing the heartbreaking news to her colossal readership in a public statement a year ago.
