I'm Amber Roberts. Just your average teenager. Life revolves around school and my best mate, Vi. Nothing too dramatic, and certainly nothing dangerous. Well. That's how things used to be. But now, my life is way more complicated: Mum and Dad have a massive secret and Vi's being all moody. But, bigger than that-I've just been recruited as a secret agent! That's right. Me. An actual spy. Exciting? It would be, if I had a clue what I was doing . . .
