The galaxy was once terrorized by the Sturm, a group of “species purists” intent on destroying any human with genetic or cybernetic enhancements. Fashioning themselves as the one true “Human Republic,” the Sturm cut a bloody swath across the stars, killing billions before finally being defeated and driven into the far reaches of Dark Space. Centuries of peace bred complacency. Everyone believed the Sturm had died out in the Dark. They were wrong. The enemy has returned and, with a brutal and decisive attack, knocks out almost all of humanity’s defenses. Now on the brink of annihilation, humankind’s only hope is a few brave souls who survived the initial attack: Commander Lucinda Hardy, thrust into uncertain command of the Royal Armadalen Navy’s only surviving warship. Booker3, a soldier of Earth, sentenced to die for treason, whose time on death row is cut short when the Sturm attack his prison compound. Princess Alessia, a young royal of the Montanblanc Corporation, forced to flee when her home planet is overrun and her entire family executed. Sephina L’trel, the leader of an outlaw band who must call on all of her criminal skills to resist the invasion. And, finally, Admiral Frazer McLennan, the infamous hero of the first war with the Sturm hundreds of years ago, who hopes to rout his old foes once and for all—or die trying. These five flawed, reluctant heroes must band together to prevail against a relentless enemy and near-impossible odds. For if they fail, the future itself is doomed.

A group of intrepid heroes must rebuild and protect civilization after a long dormant enemy shattered their once-peaceful empire in this thrilling sequel to The Cruel Stars. The Sturm, a group of "species purists" intent on destroying any human with genetic or cybernetic enhancements, returned from the far reaches of Dark Space to strike a devastating blow against humanity. Though their victory seemed inevitable, a small group of reluctant heroes managed to beat back the invading force. Now left with the remains of a crippled civilization, they must work together to rebuild—and to stand guard, in case those weren't the only enemies hiding in the dark...

With sheer weight of numbers, the Sturm's Combined Fleet of the (self-proclaimed) Human Republic are driving ever deeper into the network of worlds they were exiled from over three centuries ago. At a horrendous cost, Commander Lucinda Hardy, Admiral Fraser McLennan, Sephina L'trel, Booker3 and Princess Alessia lead the only resistance to the Sturm's overwhelming forces. Amid the ruins of a civilisation utterly corrupted by the Sturm's horrific darkcode malware, they must gather allies and weapons where they can. Old enmities must be overcome and unlikely partnerships forged. Surrounded, outnumbered and outgunned, the resistance cannot hold out. By strategy and deception, they must force a decisive confrontation with the Sturm. A final stand that will demand the ultimate sacrifice... and extreme violence.
