“We are heartbroken to announce the passing this morning of our beloved Sophie (aka Maddy, aka Mummy). She died peacefully, with her final days filled with her true loves: family and music and warmth and Christmas and joy,” the post reads. “We can’t imagine what life will be like without her radiance and love of life. Despite her illness, which she bore with unimaginable courage, Sophie counted herself truly blessed — to have such wonderful family and friends, and to have had the extraordinary success of her writing career. She took nothing for granted and was forever grateful for the love she received.”

Her first book, “The Tennis Party,” was published under the name Madeleine Sophie Wickham when she was 24 years old and working as a financial journalist.
