From ancient heroes like the rebel slave Spartacus to modern-day dissenters who defied the odds, Stand Up, Stand Out! is the ultimate guide to inspiring tales of human passion and courage.

Meet 25 of the most inspiring humans of all time! These rebels stood up for what 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 Sendler (who smuggled 2,500 children out of the Warsaw Ghetto in World War II) and Juliane Koepcke (who survived an airplane crash at aged 17, followed by nine days in the Amazon rainforest), this book is filled with incredible stories of passion and endurance. It also offers encouraging suggestions on how to make your own stand when you see unfairness.
