"Since my glioblastoma diagnosis in 2022, I have been surrounded by the love and support of so many friends, family and readers from around the world," the author wrote via Instagram in June.

Kinsella, who is survived by husband Henry Wickham and their five children, has authored tens of novels. Her bestselling Shopaholic series starred journalist Rebecca Bloomwood, who went to work at a financial magazine despite her own crippling debt. "When I come to a new book, I'm like, 'Hi Becky, let's have some fun together,'" Kinsella quipped to CBS News in 2014 of her writing process. "I step into her shoes and look at the world through her eyes and off we go. ... You're sitting alone in your room and you're tapping away [on a computer] and you hope people enjoy your book and then off it goes, but then you get somebody who says, 'Well, you know what? I read your book in the middle of the night when I was recovering from [an] operation and it got me through.' I mean, how can you do anything better in life than that?"
