Twenty years ago, Nathan Vance and his friends made a pact on a bridge to hide a tragedy they called "The Fourth Plank." Now a master of high-stakes strategy, Nate returns to his decaying hometown of Blackwood to erase the evidence before a new industrial project unearths the grave.
But as the "Structural Fatigue" of his own lies begins to take hold, Nate must navigate a deadly game of corporate sabotage and small-town secrets. To save the only people who know his truth, he'll have to decide what's more dangerous: the murder they committed, or the lengths he'll go to keep it hidden.
