Iceland's Women's Day Off in 1975 saw 90% of Icelandic women take time off from their paid and unpaid work, an experience that not only showed women how much they contribute but turned Icelandic men into supporters of gender equality. I aim to achieve the same impact in the UK.

I've taken a certain a pride in all of my books. They devour so much time and energy that you have to engage deeply or you'd go mad.

What drives me is a sense of urgency. We live in frightening times. Progress towards gender equality and vital battles to end discrimination on grounds such as race, age, sexuality and disability are stalling and in some places, reversing. This is happening because of the collapse of trust in nearly all public institutions, and in particular in politics and media, and the inescapable feeling that the current system isn't working for most people.

Writing a book is like running a marathon. You need to be fit to do it, mentally and, as far as possible, physically.

Studies show that women seeking power tend to be punished for doing so, because it goes against cultural bias. Women are expected to be likeable and pliant. We are also trained to expect any success we attain to come to us through men - by pleasing men, as good employees, good partners.

The system isn't working for most people and never has worked for most women.
