Mireille Harper

Editorial Director, Author & Editorial and Communications Consultant

I’m Mireille, an Editorial Director, author and editorial and communications consultant working at the intersection of publishing, books, culture, ideas and content.

For the past nine years, I’ve worked with bestselling, prize-winning and critically acclaimed authors to develop, shape and publish books that find their audiences and make an impact. I’m currently Editorial Director of TONIC, an imprint of Bloomsbury, where I commission and publish books that help readers think, feel and live better. My work spans editorial strategy, book development, commissioning and publishing, bringing ideas to life and connecting them with the readers who need them.

I’m also a successful children’s author . My debut book, Timelines from Black History, published by Dorling Kindersley, has sold more than 60,000 copies worldwide. I’ve also spent more than a decade writing about culture, lifestyle and ideas, with work published in British Vogue, Glamour, Good Housekeeping, GUAP, Nataal and elsewhere.

Alongside my publishing and writing career, I run an editorial and communications consultancy, partnering with authors, brands and organisations to develop ideas, refine their messaging, strengthen their editorial strategy and create compelling content. From book proposals and editorial development to brand storytelling, copywriting and communications, I help clients find their voice, clarify their ideas and reach the right audiences.

I also create books, money and home content, bringing an editorial perspective to subjects that shape how we live. Across LinkedIn, Instagram and TikTok, I have a combined audience of 75,000, creating opportunities for thoughtful storytelling, audience engagement and collaborations with brands and organisations.

Whether I’m commissioning and publishing a book, writing one, developing a brand’s voice, creating content or advising on editorial and communications strategy, my focus is the same: finding the strongest idea, telling it brilliantly and making it matter.
