Swarm: Science Fiction

The swarm was right behind her as she brought the pontoon plane down for a landing on the outskirts of the island. She eyed the sky, scanned the sea to see if the fish had swarmed yet, and made the decision that she didn't have time to get to one of the safe shelters, so she'd have to go with the underwater marina cave. It took only a minute for her to yank all the organics out of the plane before the swarm could destroy them, and then she dove over the side of the boat and swam to the shore, or nearly to the shore, to the cluster of rocks that indicated where the cave could be found. One deep breath, and under she went, grateful that this time her run hadn't included bringing back any precious livestock. Getting them under the water and into the safe cave would have been pretty nightmarish, even if successful. Even the thought reminded her of how hard the kid goat had kicked the one time that she’d had to swim for shore with him. He was now a very popular goat on the island, since he bred true and his long hair had done great things for the weavers, and he kept the nanny goats happy and popping out kids, but she hadn’t liked him very much for a while. Inside the cave, the familiar glow of the phosphorescent lichen soothed her. It was edible in a pinch, and on the first year it had been very difficult to keep it protected enough that it would survive. When people were licking rocks in hopes of getting a little something extra. Now, of course, the sea population had rebounded like crazy from the overfishing that took place before the swarms, but---
