When two missing Recon operatives returned to the compound, speculations ran wild about where they had been. Harper is certain they're infected with a deadly virus, but she's locked away in the cages, facing 10 to 20 years behind bars. Blaze thinks Harper has a shot at being released, but nobody can save Eli from Constance. Jayden is torturing him for information on his brother's whereabouts, and as Constance's newest lackey, Celdon is caught in the middle. When an outside hacker breaches the compound's firewall, Celdon becomes an unwitting participant in the drifters' scheme to bring down Recon. In the explosive fourth chapter of The Fringe, bullets will fly, loyalties will be tested, and the compound will face a war on two fronts.
