When a group of children are having a playful day at the beach, the fun of building sand castles is forgotten when they start arguing about whose castle is best. While fighting over "I," "me," and "mine," they end up destroying and abandoning the castles they so carefully constructed. The timely arrival of a magical wise man teaches the children that unlike the sand castles, it is the things we can't see that really matter most.

Delicately illustrated by the beloved and award-winning author Demi, The Secret of the Sand Castles teaches children the joy of creating a harmonious world in which to live--with an open heart and love for one another.
