<em>Last Light</em> by Alex Scarrow is the story of a coordinated terrorist attack on key Islamic holy sites, as well as most of the world's oil supplies, which effectively brings western civilization to a halt.
It deals with the immediate fallout from the catastrophe—riots, food shortage, breakdown in law & order. There's a sequel Afterlight which goes into more detail about what a post-collapse society would look like.
There's something of an emphasis on sexual violence in both books and quite a pessimistic, reactionary, view of 'feral youth' going wild in a newly lawless environment. However, they're very gripping and for page turning thrillers I found them highly believable.
The book it's based on seems fairly apocalyptic. Hopefully the show is too.
Never heard of it, but it looks really good from the Wiki page. Do you recommend it?
