Virozone

THE WORLD AS WE KNOW IT HAS BEEN RAVAGED BY VIOLENCE AND ENVIRONMENTAL DISASTER.
Society has been split into exclusive zones, protecting these limited assets - Air, Water, Soil and Fire. Each zone trades what they can to survive.
Life is difficult, particularly as a fifth zone, the Prestige Zone, takes what they like to ensure their privileged life may continue to thrive.
But when sixteen-year-old Lawlie Pearce's mother is killed, it becomes clear that the tenuous peace between the zones is on the verge of unravelling.
With a thirst for vengeance, Lawlie leaves AirZone to discover the truth and seek justice for her mother - even if she must bring down the biggest enemy of all, Sceptre, the leader of the Prestige Zone that dominates the world that is Virozone.
"I am congratulating the author, Sarah Cole, for such magnificent world building. To map out a believable living world out of nothing is something that shouldn't go unnoticed!! ... and wow, what an ending! Definitely giving this a 5 star rating and would suit readers who love YA dystopian books, and for those who have read The Hunger Games, there are elements there that will excite you." Pauline, Goodreads reviewer
