Girl Apocalypse

My name is Molly, and I am a walking apocalypse. Death on two legs.
Life on the streets of Cheshire makes you hard, but it never prepared me for this. It all started when I stole something, nothing more than a pretty trinket that caught my eye (I didn't say I was honest). Later I find out it's a carrier of black magic. A deadly spell that will end life as we know it. I have days to get it across the world and into the right hands. And only minutes before the men chasing me finally catch up.
