The Last Iron Horse. Rangers of Walden, #3

The fall of civilization didn't end the struggle - it reshaped it. With oil gone and supply lines collapsing, survival has become something more organised. and far more dangerous. At the university near Lake Ramsey, Daniel and Victoria uncover evidence of sabotage inside their fragile sanctuary. Supplies are vanishing, trust is eroding, and an approaching force led by Harnet threatens to tear down what little stability remains.
To the south, Derek returns to Whitefish to face Eric Kovach - a ruthless slaver building power along the last functioning rail line. The "iron horse" is becoming a weapon, linking broken communities under a new kind of control. With Gina and Garrett at his side, Derek moves to stop Kovach before the train becomes the backbone of something far worse than collapse. As separate struggles converge, one truth becomes impossible to ignore: Civilization isn't returning.
It's being replaced. And what comes next is learning how to survive something that still thinks it deserves to rule.
