I just stumbled upon this marble (thanks TVTropes!) and am about two thirds down the first part "Armageddon" and have to say this "book" is flat out brilliant.
To read, just start up with Armageddon 1-5 and then go forth.
A small in-take on the setting:
God, named Yahwe in this setting, is fed up with humanity not worshipping him in blind, unrelented faith as he/she/it demands and send "The Message" to the realm of earth, stating heaven's gates are closed as of now and everyone is supposed to lay down and just die to roast in hell for eternity.
Going with that, Satan proclaimed Earth his dominion and demands humanity to submit to his will, meaning of course roasting in hell.
Question: What does humanity when God basically told them to f*ck themselves and go to hell and the Devil boasts about usurping Earth and all within it?
Answer: The declare war!
That is just fine by Satan's will as he is keen on spewing some torture on those hapless monkeys, though he gets on finding out that even supersized and equally strong demons (Baldricks) in their shiny bronze armor and lighting spewing tridents are just a little itsy bitsy understrenght when dealing with modern combined arms warfare, EM hardened tanks and MRLSs raining steel on his legions of hell.
Suffice it to say they halfway through the first part, there is a literal Highway to Hell, the People's Front for Liberating Hell is raising havoc in the sixth Circle of Hell, Gaius Julias Caesar and his Guards Lucius Vorenus and Titus Pullo laugh heartily watching "Rome" and the Human Expeditionary forces are in the process of transitioning 3.6 million demons that were sent to repell the human forces from Hell.
Oh, and God's favourite pet is a giant beast capable of wreaking destruction absolutely disproportionate to its dreadful name ... Wuffles.
Count in Archangel Micheal running a drug-ring in Heaven and celestial hookers and you have a rough idea how awesome "The Salvation War" is.
And do not make the mistake of thinking my rather sensationalistic preview does the excellent writing justice, it is not a simply gag-show of mass-slaughter and comedy, but a sensible and very intelligent thought of storyline.
In other words: One hell of a read!
Any thoughts you might want to share (after reading a bit of it of course)?
