Flower of the Underworld (LET'S BE HONEST, I'M NEVER GONNA FINISH THIS)

Koré Karasoulos has no memory of her life prior to age six. Her foster mother Diane is the only family she has ever known. Her parents were Greek and that was the only thing she was ever told about them.
On her sixteenth birthday, Diane decides to have them move to Greece.
Little does she know that the move is not Diane's choice.
Her school life in Greece could be better. On her first day she is given the demon locker, manages to befriend the endearing social outcast Taylor all the while catching the eye of the Student Council President Jay Vasiliás. But that isn't even the worst of it. Exactly one month later the most feared guy in the school announces that a they are dating when they only met that morning.
All these events raise questions for her.
Why was Diane so against her learning about Greek myths?
Why did everyone act as if they had met her before?
And how exactly did she fit into all of this?
In a world where myths are real and magic exists, nothing is ever what it seems.
