This is the extraordinary story of how one small girl stopped a planetary catastrophe. It’s a very timely book, written for the child in us all, with a forceful message about the power of young people to transform the world - a theme currently demonstrated by brave young heroes like Greta Thunberg. And with magical synchronicity, the very week Greta began her lone vigil outside the Swedish government last year, over 1,000 miles (1,897 km) away in the fictional world of books, Amelie Trott took to Parliament Square, London - on a mission to avert the End of the World. It’s a family drama with an international feel - set mainly in England but with episodes in Washington DC and around the world.
