'We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed' Martin Luther King

In an era where our liberties are often under threat, Letters to Change the World sends reminders from history that standing up for - and voicing - our personal and political beliefs is not merely a human right but our duty, if we want to make change happen.

Featuring Emmeline Pankhurst rallying her suffragettes, George Orwell's warning against totalitarianism, Nelson Mandela's consoling his children from prison, Time's Up condemning abuses of power, and much more, this collection will inspire you to stand up and speak up - now, for what really matters.

'Remarkable, timely ... At a time of political uncertainty, the collection demonstrates the importance of speaking truth to power' Guardian
