Bella Mackie is a former journalist who previously worked for The Guardian and Vice News. She writes a twice monthly Vogue column. Her first book, Jog On, was a memoir about mental health and running. It was a number two bestseller (just underneath Michelle Obama, which is a hallowed spot).

Since then she's written an accompanying journal to encourage others to try exercise more for their minds than their bodies. Bella's first foray into fiction, How To Kill Your Family, came out in July 2021 and ended up in the number one bestseller spot. Bella lives in London and spends a lot of time wrangling her large stupid dog.
