Holly started her writing career as a news journalist, where she was nominated for Best Print Journalist of the Year. She then spent six years working as an editor, a relationship advisor, and general 'agony aunt' for a youth charity - helping young people with their relationships and mental health. Inspired by what she saw, she started writing teen fiction, including the best-selling, award-winning 'Spinster Club' series which helps educate teenagers about feminism. When she turned thirty, Holly wrote her first adult novel, examining the intensified pressures on women once they hit that landmark.

Alongside her writing, Holly has a keen interest in women's rights and is an advocate for reducing the stigma of mental health problems. She's helped create online apps that teach young people about sexual consent and is an ambassador for Women's Aid.
