Chapter 1, in which there's too much exposition

Sirens. Most people think of them as monsters, an idea you don't completely disagree with. The sirens you know certainly fit that description, for the most part. An opinion that wouldn't be an issue if the sirens you knew didn't happen to be your friends and family. Things go wrong and you're thrust into a situation facing the world's mightiest heros, and a villain who's much more than he seems.
