During an apocalyptic battle against murderous machines and hardened soldiers a lone salvage marine turns the tide with a devastating counter attack. Having revealed herself as a consummate warrior, Jada Sek is welcomed into the ranks of the Dire Swords, an elite fighting force loyal only to the contract.
As the other marines return to their salvage duties Jada and her new comrades, each as haunted by the ghosts of their past as she is, plunge yet further into necrospace. They are repeatedly deployed to disrupt and destroy the endeavors of corporate competitors, and along the way discover that the enigma of the machine race is more sinister and complex than any imagined.
Surrounded by the specters of an ancient holocaust and forced to face her inner conflict, Jada must make a choice. When the money ceases to matter, when surviving loses its significance, and the thrill of taking the fight right into the teeth of the enemy seems like the only truth left in this scrapyard of a universe, it is time to let the marine die so that the mercenary can be born.
