Jill Marshall is a global storyteller and founder of GirlPower Publishing, the home of unforgettable characters, bold narratives, and IP-ready storyworlds.
 

A former corporate strategist/specialist with blue-chip business expertise and a Cambridge education, Jill traded boardrooms for books - and has since written 28 acclaimed novels spanning middle grade, YA, and adult women’s fiction. Her breakout hit Jane Blonde: Sensational Spylet broke Macmillan’s debut sales records for a children's book, launching a bestselling series published in 22 countries and 11 languages, with film and TV interest from Oscar-winning producers and familiar Hollywood teams.
 

Jill’s work is defined by strong female leads, whip-smart humour and emotional resonance. From spy school to witch fights, neurodiverse romances to second-act reinventions, her storyworlds capture the hearts of readers - and the attention of producers looking for the next big universe to build on screen.
 

She is also the host of The Download podcast and a sought-after strategist for creatives, founders and thought leaders. Through her studio Wisewoman & Wordsmith, Jill combines intuition, narrative intelligence and business insight to help shape the futures of people - and their platforms.
 

Now spearheading a new era of multi-format, female-powered storytelling, Jill is growing GirlPower Publishing into a vibrant IP studio and media brand designed to entertain, empower, and evolve ... one character at a time.
