Brimstone

And I beheld, and heard an angel flying through the midst of heaven, saying with a loud voice, Woe, woe, woe, to the inhabiters of the earth by reason of the other voices of the trumpet of the three angels, which are yet to sound!
Revelation 8:13
Jesus warned that the Great Tribulation would be a time of unmatched tumult and human suffering. As Emilio and Mackenzie are finding out, the Messiah's words were no hyperbole. They've survived the Seven Seal Judgements and the First Trumpet. But the coming wave of destruction foretold by the prophecies will bring about chaos they never could have imagined.
Upon arriving back at the resistance compound in Kentucky, Emilio and Mackenzie discover a deep schism among the members. Multiple people are attempting to fill the power vacuum left by Hinkle's death. If the group can't work out their differences, they'll never be able to stand against the Global Order.
The Third Trumpet sounds and a comet strikes the earth which releases heavy toxins into the environment. Chemicals from the asteroid leach into the ground and poison the water supply. The group rushes to find a solution, but some of the members give up and head for the nearest OASIS city in Atlanta. Emperor Lucius Alexander promises distilled water and sustenance in exchange for the souls of those who will bow only to him.
As if Emilio and Mackenzie didn't have enough trouble already, they're spotted by Global Order peacekeepers while on a mission to salvage materials for a lager water distillation system. If they manage to survive the firefight, more tribulation and turmoil await. They'll need to be strong in body, mind, and spirit if they have any hope at all of surviving the coming catastrophe.
As with all works by Mark Goodwin, this book contains no profanity and no embarrassing sex scenes. However, if you're offended by conservative principles and references to Scripture, this book might not be for you.
