Bagge got the idea for it when he heard that South Korean madman Kim Jong Il proudly boasted that his country had the capability to hit Seattle with a nuclear warhead, but at that time the US were so busy with Iraq it didn't even rate a mention in the news. But it sure scared the hell out of Mr Bagge, so he came up with Apocalypse Nerd, a story about two pals who head out to the woods for the weekend, meanwhile North Korea does go ahead and wipe out Seattle with a nuclear bomb.
The book has loads of cool scenes of mankind reduced to savagery, so if you dig all those 'end-of-the-world' type movies (and who doesn't?) then you'll love this as much as I did.
