Worst Case Scenario:
The Road, by Cormac McCarthy
Post-Apocalyptic fiction has just recieved the 'literary treatment" from Cormac McCarthy, its called "The Road". Cormac McCarthy (All the Pretty Horses, The Crossing, Blood Meridian) is one of the best american writers alive.
His writing can be difficult, not for the squeamish. Unflinching looks into the heart of darkness; the amoral voilence of the American West in "Blood Meridian" and post-apocalyptic despair and hopelessness in "The Road".
"The Road" takes place 7-10 years after a nuclear war. The sun no longer shines. Nothing grows. The birds are dead. Almost everything is dead and grey. Drifts of ash blow around and cover everything and destroy the survivors lungs.
A father and son have survived so far, but there is little reason TO survive. Their friendship is really the only thing they have. The communes have mostly been overrun. If communities do exist, they mostly want to kill you and take your stuff and probably eat you.
Roving bands of thugs in dust masks just go around 'finding whatever they can to eat". Which is mostly other survivors. Only the worst psychopaths are left, mostly. Rapists and cannibals.
The book is realistic in its look into the human heart, but not realistic regarding accurately presenting the after effects of nuclear war. Its more poetic on that level.
It's more like a post apocalyptic "Waiting for Godot". I almost posted this in psychology. Its sooo much worse than anything we will likey face it almost helps you face some "worst case peak oil scenarios". Unless you think it will be a nuclear fight, then you'll just be more terrified.
This is an incredibly powerfull book, be prepared to be shaken. Yet still it manages to have hope even when all is hopeless.
Very intense experience.
