Isis took a breath and jumped into the pool, landing with a splash. Suddenly, she was enveloped in warm sea water and then she surfaced again, breaking into the air. As she pushed her dripping hair back and away from her face, the moonlight began to slide over the rippling water and she was mesmerised. She didn't know when she had clasped hands with the two girls beside her or how the water had gotten so hot. For some reason, she just didn't question it until the bubbling water had stopped and the moon had moved again.
A wash of calm rushed over her before she finally came back to her senses. "Let's get going, shall we?" She smiled, hoping she'd have strong enough lungs to make it. She didn't swim as much as she would have liked to. Taking a deep breath, she dove beneath the clear water and followed the other girls through the darkness. There was a moment of hesitation before she followed they through the small hole, panic rising quickly in her chest. She was almost persuaded to stay behind in that beautiful cave on her own. Shaking her head, she pushed herself forward and through the entrance.
Her lungs began to burn half way through the tunnel and she pushed herself faster. She'd only have a few more seconds before she had to breathe. Iris surfaced with heavy, sputtering breaths and a reddened face from holding in air. She coughed, brushing her hair back again and trying to catch her breath and stay afloat.
Getting to shore was difficult. The effort of swimming out there had exhausted her and she found the distance difficult to close. When she collapsed onto the sand, relief flooded her bones and she sighed, closing her eyes and taking a deep breath in to relax herself again. The panic in her chest fell back, the calming lapping of the waves against her clothes reminding her that she was no longer trapped inside and everything was open and free.
