Out of the Dark

And if the Shongairi took a few knocks in the process, all the better. Now, Earth is conquered. The Shongairi have arrived in force, and humanity's cities lie in radioactive ruins. In mere minutes, more than half the human race has died. Master Sergeant Stephen Buchevsky, who thought he was being rotated home from his latest tour in Afghanistan, finds himself instead prowling the back country of the Balkans, dodging alien patrols and trying to organize scattered survivors without getting killed. And in the southeastern US, firearms instructor and former Marine Dave Dvorak finds himself at the center of a growing network of resistance putting his extended family at lethal risk, but what else can you do? On the face of it, Buchevsky's and Dvorak's chances look bleak, as do prospects for the rest of the surviving human race. But it may well be that Shongairi and the Hegemony alike have underestimated the inhabitants of that strange planet called Earth
