Maisie vs Antarctica

I'm Maisie. I write stories about adventures and heroes.
So I know for a fact my dad is not a hero.
But then he crashed our plane into Antarctica.
Now we're freezing. A leopard seal wants to eat me. And no one's coming to rescue us.
And Dad has a secret. A totally impossible secret. One he's kept from me all my life.
I'm going to find out what it is. If Antarctica doesn't kill me first.
