To survive without them

Have you ever dreamt of a world with no adults? admit it, you thought it would be great right? no-one to tell you what to do or tell you off, but for a young girl of the age of sixteen, this is her life.
She must survive to look after her siblings and herself. The world has turned into a crazy place with tribes ruleing and with street fights and the cities damaged. Its a place where kids rule, only its how they chose to survive that can get them through in the end.
P.S. the book does get better when it goes further in so if you do read it keep reading for some more action. Its also slightly a romance book as well as a science fiction, Adventure and teen fiction.
Enjoy and comment/ fan me for any other stories I have such as Drop Off and your suggestion wills be greatly appreciated.
