It is now 2035 and Gen and Nate MacGregor's family have overcome the traumatic upheaval in their lives since the oil ran out. Five years on and they are finally looking forward to some 'quiet' years together.
The rest of the world though, is not surviving these times quite so well as the MacGregors. Thousands have died from starvation. Wars have broken out in many countries over dwindling resources. Cities have crumbled as the world's leaders and infrastructure has failed, leaving survivors to deal with life in whatever way they can. Many who have made it this far, have done so with cunning and ruthlessness.
The cruel twist of fate's knife is felt once again when newcomers to Arrow Valley betray their generosity and Gen finds herself in danger, again, of losing everything she loves.
Will the strong head of this family, once again show true-grit in the face of death? Battles of the mind and heart cannot be waged with swords.
