'Zone is one continent divided into several neighbouring regions, both allies and enemies. In each region an army of specially trained and enhanced humans are known as Soldiers, created for the defence of each city - and the destruction of their enemies. Five years after the murder of Sage's brother, she has become Lion Crest's top Soldier in order to seek revenge. Yet when a chance encounter leads to the blurred line between right and wrong. Sage discovers that not all is what she thought and her brother's murder was the beginning of something much darker.'
