Saturnius Mons (Ruins of Empire Book 1)

The battle for the future of humanity begins on Titan.

A Corporation ship has landed on Saturn's largest moon. Its mission is to exploit the world's vast resources and enslave a society made up of people from a long-lost Terrestrial colony. Before it is too late, Viekko Spade, a warrior from the Martian steppes and his fellow explorers must end Corporate ambitions on the moon before it can spread to the rest of the solar system.

But there is a dark secret hidden inside the terraformed forests of Titan. Ancient hatreds are building and a religious civil war is on the brink of extinguishing all human life on the moon. It's a race against time to unite the warring tribes on Titan against the Corporation military forming outside its city's walls. But nothing on Titan is as it seems and as the situation devolves into bloody chaos the choice must be made. Give in to the Corporation's demands or continue to fight and risk the life of every person on the moon.
