Not a single country anywhere in the world has achieved gender equality. In more than a few countries, progress for women has stalled or is reversing. Voters in the United States chose a misogynist over a female candidate for president.

Yet in many of these countries, the majority of politicians and business leaders profess to believe in gender equality - as well they might. One report predicts a boost to global GDP of £8.3 trillion by 2025 simply by making faster progress towards narrowing the gender gap. Researchers point to many other potential benefits, too, not least in improved relations between the sexes and a healthier, more peaceful planet.

If gender equality promises benefits not just to women but to everyone, why aren't we embracing it? And how can we speed the pace of change? Fewer than 9 percent of world leaders are female, but the few women who have broken through include towering figures such as Angela Merkel. Could 50-foot women save the day?

These questions have gripped journalist and author Catherine Mayer since she accidentally founded the Women's Equality Party in March 2015 and watched it grow in months from an idea to a vibrant political force with more than 70 branches across the UK. In Attack of The Fifty Foot Women, her insightful, revelatory, often hilarious and hugely inspiring book, she tackles those questions and many more, sharing inside views and experiences from building a party and bringing together global research with analyses and interviews based on her own far-flung research.

And she goes further. Campaigning for the Women's Equality Party ahead of elections in May 2016, she noticed that many people found it hard, in the absence of any real-life examples, to envisage a gender-equal world. So she takes us there, to the place she calls Equalia. What is it like? Does gender equality make for a society that is more equal in other ways, too? Who does the low-paid jobs? How does gender express itself in a place freed from gender programming? What's the sex like? What's on the telly?

This audiobook includes an exclusive roundtable discussion between author Catherine Mayer; narrator Tanya Moodie; and Head of Policy for the Women’s Equality Party, Halla Gunnarsdóttir.
