The Aftermath

I dont remember anything about my childhood. Was I anything like I am now? I dont remember my family or my friend, parents or teachers. I wish I did. I must be somewhere around the age of sixteen or seventeen but I have lost track of the years. My name ... Hope.
Throughout the years, many world disasters have struck on countries but after the biggest tidal wave wipes out most of Europe and North Africa, the aftermath effects the whole world.
Hope is a teenage girl who looses her entire family apart from her younger brother. She can't remember his name or age but they are all eachother have. When Hope realises the whole world is falling apart, she leaves her destroyed home and embarks on an adventure that she is not prepared for.
When every day is a fight for survival who knows when it may be your last day, but the question is, how long can she survive?
