Yolanda Renee King never met her grandfather, Dr. Martin Luther King, Jr. But the 13-year-old is one of the countless activists inspired by his actions. As a young activist devoted to fighting racial injustice and gun violence in schools, that's a dream that fuels her further. Nicole Tadgell is an award-winning watercolor artist whose work spans more than 30 luminous picture books for children. When she's not drawing, Nicole enjoys practicing Tai Chi and watching Doctor Who.
