Pinkett Smith's "Girls Hold Up This World," published by Scholastic, is aimed at empowering girls like her 4-year-old daughter, Willow.
"I wrote the book for Willow and for her friends and for all the little girls in the world who need affirmation about being female in this pretty much masculine world," said Pinkett Smith, wife of fellow actor Will Smith.
The book is illustrated with photos of women and girls taken by Pinkett Smith's photographer friend, Donyell Kennedy-McCullough.
"I really tried to capture different sides of femininity," said Pinkett Smith. "I want girls in the world to feel powerful, to know they have the power to change the world in any way they wish."
