Dies the Fire by S M Stirling
The year is 1998 and a strange electrical storm over the island of Nantucket suddenly causes all electronic devices to stop functioning! Cars and trucks stop in the middle of street, planes fall out of the sky and the world is changed forever. Small groups of people realized that this is not a temporary event and begin gathering seeds, farming equipment, livestock and move out to the country to survive. The cities go first with disease and starvation and the more ruthless individuals' are building armies for conquest.
So what would do if the world ended tomorrow? What skills do you have that would help you survive?
