In this uplifting collection of true stories, readers are introduced to real-life heroes and heroines who have chosen to act in kindness, even when they have faced terrible persecution, prejudice, disaster, and illness. These stories are designed to empower children to make positive choices in their own lives by embracing kindness as their superpower.

Stories include Harriet Tubman’s remarkable rescue missions to free enslaved African Americans, the French village of Le Chambon-sur-Lignon’s protection of Jewish refugees under Nazi persecution during WWII, and the brave people who volunteered to clean up after the nuclear crisis in Japan. Also included are everyday examples of acts of kindness to protect nature and lift up others, even complete strangers.

Let’s Fill This World with Kindness explores the science of how our brains and bodies behave when we give and receive kindness. Featuring biographies of thinkers and philosophers from across different cultures who have celebrated the power of goodwill toward others, each chapter concludes with a list of questions for readers to help them reflect on the ways they too can be a kindness superhero.
