The Darshik war machine is flagging, but the war is far from over. Even as an exhausted Federation military tenses up for a counterattack after repelling the last Darshik invasion, reports are coming in of a new, more powerful class of ship that's striking deep into Terran space. Captain Jackson Wolfe has been given the fleet's newest, most advanced destroyer and tasked with eliminating this new threat before it can claim any more human lives. What he finds, however, is immeasurably more dangerous than just some new class of starship....

The Federation's military command is desperate, and with their fleet still in tatters, they make a last-ditch effort to free the planet: They pull Captain Jackson Wolfe out of retirement and put him in command of a ship they hope can get past the defending armada and provide support to the beleaguered Marines and civilians fighting on the surface of the contested world. There is no reasoning with this enemy. If the Terran Federation wants their planet back, they will have to pay the price.

The colony on Haven-7 has gone rogue. The colonists have split into two factions: the Techborn and the Dusters. The Techborn have always ruled the planet.

Their weapons are getting old, and radiation leaks from the aging reactors have created mutations. Some of these, like their brutish troops known as Tuskers, have proven useful—but others are abominations.
