The EMP

When a huge EMP hits Earth, all earths power and water and anything that has anything to do with electricity dies. Doesn't work. Stops.
Three 16-18 year olds are affected by this EMP, emotionally and physically. When they meet each other they group up and figure out how to stop and survive the EMP.
Will they figure out who set off the EMP? Will they stop it? And most importantly...
Will they survive?
