One woman. One seed.

One hope for the future.

Thayu nyumba -- Peace, my people.

Wangari grew up in the shadow of Mount Kenya listening to the stories about the people and land around her. Though the trees towered over her, she had loved them for as long as she could remember. So strong, so beautiful, how the trees made her smile.

Wangari planted trees one by one to refresh her spirit. When the women came to her for help with their families, she told them to do the same. Soon the countryside was filled with trees. Kenya was strong once more. Wangari had changed her country, tree by tree.

Donna Jo Napoli tells a story inspired by the life of 2004 Nobel Peace Prize recipient Wangari Maathai that will touch the hearts and spirits of all who read it. Kadir Nelson's stunning collage illustrations honor the spirit of a land and of the woman who saved it.
