Cantarella Chapter 1 and Prologue {Poison}

Cantarella Noir is not a normal Freshman and she doesn't go to a normal highschool. No, she goes to what is called the Bureau, a large castle-like building sitting cozily in the mountains of Wisconsin. And her dad just happens to own the whole place.
That's not even the bad part. What's bad about the whole situation is that she's and agent, her father uses her to kill/poison targets because she's immune to any poison or chemical- including medicine- and that there are two guys on her 'team' that annoy the hell out of her. One's Cedric; tall, red-head with some nice muscles but serious mood problems. Then there's Stephan, her guard - as proclaimed by the man called her father. He's laid-back and generally gives her the vibes that he doesn't care about the Bureau, but the guy has some serious skill when it comes to fighting.
And then something weird happens. A friend goes missing. Next thing she knows, Cantarella is staring right at the presumably dead body of her best - and only - friend with Stephan standing as the only suspect.
