Emperor Ping, the boy emperor known for his love of harmony, sets a challenge to the children of his kingdom: show him the greatest power in the world. "To know the greatest power in the world is to know the greatest peace," Emperor Ping announces. "Whoever knows this harmony will become the new prime minister." The children get to work right away and have many bright ideas. The greatest power must be weapons It must be beauty It must be money But as a young girl named Sing reflects upon the challenge, she wonders how any of those things, which cannot last forever, could be the greatest power in the world. She is certain there is something even more powerful, and the source of this power will surprise and delight her.A companion to Demi's stunning picture book "The Empty Pot, The Greatest Power" continues the story of Ping now that he has become an emperor. With striking artwork and a lovely, lyrical text, this next chapter in Emperor Ping's life is sure to enrapture young readers.
