Greta Thunberg is not alone: there is now a worldwide movement. Young female rebels are taking to the world stage. They are campaigning for clean drinking water, opposing the gun lobby, mobilising against child marriage and child labour. In order to achieve their goals, they are speaking at the United Nations General Assembly in New York, at the Economic Forum in Davos, at climate conferences or at the "March for Our Lives" in Washington. Their influence is immense; a single speech can shake global corporations such as Siemens.

Behind the young activists, just a Tweet away, stands a whole generation. The book introduces the key players, for example Emma González and the Indonesian sisters, 10 and 12 years old, who managed to bring about the prohibition of single use plastic on Bali, but it also follows up the fundamental issues: who brings them out onto the streets, what motivates them?
