Nobel Peace Prize nominee Nathan Law has experienced first-hand the shocking speed with which our freedom can be taken away from us, as an elected politician arrested simply for speaking his mind.

He remembers what it is like to lack freedom - and his father\'s precarious three-day escape from China in a small rowing boat.

When authoritarianism makes gains around the world, demanding our silence as the price of doing business, it poses a challenge to democracy everywhere.

In this passionate rallying cry, Law argues that we must defend our freedom now or face losing it for ever.
