Shattered Skies: Cruel Stars #2John Birmingham
With their advanced tech rendered null by the Sturm's attack, humanity face certain annihilation. Their only hope lies with a few brave souls who survived the initial onslaught - these five heroes might be humanity's only hope.
CENTURIES AFTER THEY WERE DEFEATED AND EXILED TO DARK SPACE, THE STURM HAVE RETURNED.
The Sturm, an empire of species purists, have returned from the farthest reaches of Dark Space to wage a war against what they call mutants and borgs: any human being with genetic or neural engineering. In a sneak attack, they overwhelmed almost all of humanity's defences, blasting vicious malware across galaxy-spanning networks: dark code that transformed anyone connected to the system into a mindless psychotic killer. The Sturm's victory seemed complete, their final triumph inevitable, until one small band of intrepid, unlikely heroes struck back.
