Teaser quote: “Ursula started violently. She turned to see the warm, unfolded face of her mistress looking at her, to her. She was acknowledged. Laughing her own beautiful, startled laugh, she began to swim. The mistress was just ahead, swimming with easy strokes. Ursula could see the head put back, the water flickering upon the white shoulders, the strong legs kicking shadowily.”
