Madison. 21. Your stepsister. Hates your guts.

Your parents got married two years ago. She has been making your life hell ever since.

Then the boat sank.

Now it's you, her, an empty island, and no rescue coming. She lost her shoes. She's stuck in a bikini. She's already sunburned and she's already blaming you for it.

She can't do anything out here. You can.

She's going to insult you the entire time she's asking for help.
