Fog 2052 [EPUB ebook] 

In 2052 a deadly fog has coated the entire earth, splitting the world in two. Peace reigns in the Lower World city of Cevario, until disappearances, mysterious deaths and cryptic messages lead City Guardian Conner on a mission to save his people.
His quest to find answers uncovers a plot more sinister than he could possibly ever imagine. There is a force gathering out in the Wastes, that threatens the existence of the entire Lower World.
With only a small band of fellow Guardians, a Scientist from the Upper World, and an eccentric old man that keeps following him though the city, can Conner overcome his own personal demons and lead a team strong enough to fight the impossible odds coming their way?
