Prologue

When a demigod comes to Camp Half-blood and can control water, immediately everyone believes that they are a child of Poseidon right?
Not in Kai's case. She is not the daughter of Poseidon although she has many of his abilities.
However she can not let anyone know about her godly parent, for it could mean her life.

This isn't about being the daughter of Poseidon, this is about becoming one.
