Napí is a young Mazateca girl who lives with her family in a little village on the bank of a river in the state of Oaxaca in Mexico. Each afternoon the family sits beneath the shade of a huge ceiba tree and listens to the grandfather's stories. As Napí listens, dreamily, the afternoons take on different colors in her imagination - orange, purple, violet and green. She finds nighttime along the river just as beautiful as the trees fill with white herons settling on their branches. The ceiba tree sends Napí dreams every night, and in her favorite one, she becomes a heron, gliding freely along the river.

Domi's vibrant palette and magical illustrations are a perfect complement to this imaginative story.
