When the future looks dark, courageous kids bring light and hope into the world. Forty true stories celebrate kids who have protested, prayed, rebelled, saved lives, earned a fortune, lost everything, become world-famous, or fought to survive war and oppression. Fearless kids, feral kids, Olympic champions, human-rights crusaders, climate-change warriors, princes and prisoners, workers and whiz-kids - they all show the true courage of kids.

From the distant past to the present moment, kids have made their mark on history; and now they're set to change the world.
