Grey Flesh Flies [EPUB ebook] 

The end of the world is pretty damn nigh……but it ain’t over yet. Misha Cafferly and Judge Hawkins are still on the road, still somehow breathing after all these months, and they’re damned if they’re giving in now. There’s hope on the radio.But the soil is poisoned, the water is foul, the bugs have become killers, the greys are everywhere, and now the terrible Sisters are even turning the survivors’ own minds against them…Time is running out.
