The mermaid princess, Sara, lived in this castle under the sea with her father the King and her five older sisters. All day long they played in the great halls of the castle. The large amber windows were open, and the fish swam up to the princesses and ate bits of food right out of their hands.
Although Sara loved her family and their peaceful blue world she longed to one day see the sky, the moon and, most especially, the humans she had heard so many stories about.
"When you have reached your fifteenth year," said her father, "you will have permission to swim up out of the sea, to sit on the rocks in the moonlight, while the great ships are sailing by; and then perhaps you will see the humans you dream of."
Sara waited impatiently as each of her older sisters turned fifteen and made their voyages to the surface world.
