In her new audiobook, Invisible Women, award-winning campaigner and writer Caroline Criado Perez shows us how, in a world largely built for and by men, we are systematically ignoring half the population. She exposes the gender data gap - a gap in our knowledge that is at the root of perpetual, systemic discrimination against women and that has created a pervasive but invisible bias with a profound effect on women’s lives.

It's the 21st century, and although we tried to rear unisex children - boys who play with dolls and girls who like trucks - we failed. Even though the glass ceiling is cracked, most women stay comfortably beneath it. And everywhere we hear about vitally important "hardwired" differences between male and female brains. The neuroscience that we read about in magazines, newspaper articles, books, and even scientific journals increasingly tells a tale of two brains, and the result is a validation of the status quo.

The Rosamund Tea Rooms boardinghouse, where she lives with half a dozen others, is as grey and lonely as its residents.

In this personal, eloquently argued essay - adapted from her much-admired TEDx talk of the same name - Chimamanda Ngozi Adichie offers listeners a unique definition of feminism for the 21st century, one rooted in inclusion and awareness.

In February 2014, Reni Eddo-Lodge posted an impassioned argument on her blog about her deep-seated frustration with the way discussions of race and racism in Britain were constantly being shut down by those who weren't affected by it. She gave the post the title 'Why I'm No Longer Talking to White People About Race'. Her sharp, fiercely intelligent words hit a nerve, and the post went viral, spawning a huge number of comments from people desperate to speak up about their own similar experiences.
