Chasing Down Mermaids

Life under the sea is far from easy. Mermaids hide in fear of being claimed by the ruthless mermen. The thought of being dragged to shore and mating with one of those monsters terrifies Sirena to her core.
The only merman she has ever seen was her father. He was cruel to both her and her mother. That is why she fled at the age of six. She has lived alone ever since.
She knows she has to hide from all other creatures, for she is no normal mermaid. What happens when she is found, by the King no less?
