Meet 25 of the bravest humans of all time!

These fascinating rebel heroes stood up for that they believed in, spoke out against injustice, and overcame impossible obstacles. From world leaders such as Gandhi and Nelson Mandela to unsung heroes like Irena Sandler (who smuggled 2,500 children out of the Warsaw Ghetto in World War 2) and Juliane Koepke, who survived an airplane crash aged 17, followed by 9 days in the Amazon rain forest; this book is filled with incredible and inspiring stories of passion and endurance.

What would you do to stand up for what you believe in?
