The thing is, everyone thinks that she's just normally scared of water. But the real problem is, is the second she touches even one drop of water, she'll only have 10 seconds to hide before re she turns.
Into a mermaid. Katelyn has to hide on land in her human form, because the pirates at seas has killed many of her kind, so it's to the point where mermaids are almost extinct.

They have such a big problem with mermaids because about a 100 years ago the mermaids killed the humans king and queen.
Little does Katelyn know, one of her friends found out her secret. And the results of this were shocking.
