You might not have heard of Liane Moriarty, but you probably will know about Big Little Lies – Moriarty’s most famous book, which was turned into a hit TV series starring Reese Witherspoon and Nicole Kidman last year.
Now promoting her eighth work Nine Perfect Strangers, the Australian author says she wouldn’t even have taken up writing if it hadn’t been for her sister.
“Sibling rivalry made me start writing,” she tells BBC News.
“My sister, Jaclyn Moriarty, had her first novel accepted for publication at the same time she was doing her PhD at Cambridge.
“We both wanted to be writers when we were little and I was so envious of her that that’s what drove me to write my first novel.
“I’m very grateful to her for my inspiration. I don’t think I would have written it – it gave me that push to finish it. It is my dream job!”
Both sisters have ended up as successful authors, with Jaclyn known for her novels aimed at children and teenagers.
Liane’s stories are decidedly more grown-up, and her new book follows nine people who enrol on a 10-day wellness course at a country retreat in Australia.
