13 year old Crystal, is turning 14 on September 10th. Her parents are finally giving her the ideal birthday present she's always wanted, a birthday party.
Assuming it would be the best birthday party of her life, she thinks things will go perfectly fine. She places her birthday at Crystal Cave, breaking tradition of going to Crystal Cove usually for everybody else's birthday.
When she finds a secret opening in the cave during a simple game of hide and seek with her family, things start to turn in to an unexpected twist.
Crystal wakes up to another regular day of waking up for school. Until, she finds something around her neck. A Crystal moon shaped necklace which she doesn't realize is cursed.
Every full moon around midnight, she will turn in to a mermaid.
