Today is the End of the World

Today is The End of the World. And so was yesterday. And the day before. And it will be tomorrow. Today is The End of the World, and everyone is coming to your backyard tonight to watch it happen. There's just one problem: your best friend Echo is missing, and it is your job to find her. And tomorrow, she will be missing. And tomorrow, you will find her. She’ll remember, but you won’t.
