... it was a while before they realized that a mermaid had surfaced at the shallow end of the pool. Her hair was pale and silvery and her nails were a shimmering blue. Between each finger there was a thin webbing, of the sort you might find on a newborn seal or a duck.

"What are you two staring at?" the mermaid said when she turned and saw the girls gaping.

Her voice was as cool and fresh as bubbles rising from the ocean. She was as beautiful as a pearl, with a faint turquoise tinge to her skin and eyes so blue they were the exact same color as the deepest sea. But her watery beauty didn't mean the mermaid knew her manners.

"Stop looking at me," she demanded, as she splashed at the girls. "Go away!"

The mermaid's name was Aquamarine and she was much ruder than most creatures you might find at sea. At sixteen, she was the youngest of seven sisters, and had always been spoiled. She'd been indulged and cared for and allowed to act up in ways no self-respecting mermaid ever would.

Her disagreeable temperament certainly hadn't improved after spending two nights in the pool, tossed there like a stone or a sea urchin at the height of the terrible storm. Chlorine had seeped into her sensitive skin and silver scales dropped from her long, graceful tail. She hadn't eaten anything more than a mouthful of that horrible herring the girls had strewn into the pool.

"You heard me," Aquamarine said to Hailey and Claire, who were mesmerized by her gleaming tail and by the way the mermaid could dive so quickly, she disappeared in a luminous flash. When she surfaced through the seaweed she was not pleased to see they were still there. "Scram," she said. "Stop bothering me."

The mermaid glided into the deep end of the pool, the better to see Raymond at the snack bar. She had been watching him ever since she found herself stranded in the pool. His was the first human face she saw. She gazed at him with a bewildered expression, the sure sign of a mermaid in love.
