From the back of the book:
The end has come...
Humanity has fallen, the survivors fight to live each and every day. Most people have congregated into massive walled cities called beacons.
A race of squid-faced beings called the Ancient Ones have risen from the depths of the Earth and now seek to claim the planet for themselves. Their ancient enemy the Angelics are here as well but they seem to only be watching.
You are a hero, you trek outside the safety of the beacons for wealth, adventure and survival.
As the human race teeters on the edge of extinction, will you be the hero that saves us all?
