What is The Power We Hold?
"Read this fierce, poetic reclamation of the body’s brilliance, and let it change everything.” - Victoria Song, Wall Street Journal Best-Selling Author of Bending Reality
As the creators of new life, women’s bodies are designed with an incredible intelligence: we feel more, sense more and respond more deeply. And unlike what we have been led to believe, that sensitivity is not a weakness...it’s an ancient form of leadership.
Your body is a barometer of balance, and your symptoms are the way it communicates when something is out of alignment - individually or culturally. When you learn to listen, you don’t just heal. You reclaim your vitality, clarity, and power to create the life and world of your dreams.
This book is not about fixing yourself. It’s about releasing what was never yours to carry, and stepping into the woman you were always meant to be - vibrantly healthy and powerful.

The reviews from experts speak for themselves...
Finally, a book all women have been waiting for and need. The Power We Hold confronts the lies, silencing, and gaslighting that have separated us from our deepest truth. Isabella Mainwaring hands us back our authority - the voice of intuition, the wisdom of spirit, and the power we hold within. As someone who has spent a lifetime awakening intuition around the world, I can say with certainty: this book is bold, liberating, and essential for every woman ready to rise.
Sonia Choquette, New York Times bestselling author of The Answer Is Simple: Love Yourself, Live Your Spirit
"This book is dangerous – in the best way possible. Isabella exposes the systems that have kept women’s bodies misunderstood and misdiagnosed for generations, and she does it with unapologetic brilliance. The Power We Hold is equal parts science, rage, and reclamation. Every woman who’s ever been dismissed, disbelieved, or gaslit by medicine needs this book like oxygen."
Dr. Jolene Brighten, FABNE, MSCP, author of Is This Normal?
"The Power We Hold is a seismic reclamation. Isabella Mainwaring doesn’t just speak truth, she embodies it, offering a rare transmission that fuses science, somatics, and soul. This book will rewire your understanding of power, pleasure, and the intelligence of your own body. Isabella reminds us that we’re not broken – we’ve just been living in systems that gaslight our brilliance. Her Root Restoration Framework is a quiet revolution, one that doesn’t demand obedience from the body, but invites it home to safety, aliveness, and power. Read this fierce, poetic reclamation of the body’s brilliance, and let it change everything."
Victoria Song, Wall Street Journal best-selling author of Bending Reality
"I cried tears of relief reading this book. For so long “women’s issues” have been relegated to our biology and psychology being inferior. Women have been led to believe that their difficulties are self inflicted. The Power We Hold shatters this illusion one chapter at a time. Isabella Mainwaring skilfully identifies the systems that oppress women’s power AND the science + soul that has the capacity to liberate women’s power. The world needs this book.”
Tamu Thomas, author of Women Who Work Too Much
“This book holds the code to return safely back to your power. A power resting in the body which Isabella, scientifically, holistically and humanly justifies has long been withheld, mistrusted and denied. It is not just an instruction to follow, but a life changing alarm bell for women to shift from surviving to thriving, with our health not failing as a consequence but being the very key through which we unlock our fullest potential. This book is a deep calling, which belongs firmly on the bedside table of the women who are ready to rise and reconstruct a better life, for today, tomorrow and our collective future.”
Henika Patel, founder of the ‘School of Sensual Arts’ and author of the book ‘Sensual: connect deeply, express freely, love intimately’
This book is a roadmap to remembering what the world made you forget
That your body is not betraying you - it’s protesting a patriarchal world that doesn't have women's wellbeing in mind.
That your symptoms are not flaws - they are a source of wisdom guiding you back to your full power.
That your health is not only personal - it’s environmental, cultural, and relational.
In this book, you’ll learn how to:
- Decode the deeper messages behind your symptoms
- Release stress, unprocessed emotions, trauma and inherited patterns
- Cultivate safety in mind and body
- Build rhythms that support your lasting wellbeing and create tangible change
But this isn’t just a book. It’s an identity shift.
A reclamation of women's health, power, and intelligence.
A free Movement Toolkit will be available once the book launches - a resource you can use in book clubs, circles, or on your own to join the ripple of women remembering their brilliance, together.
