Sounded a lot like all of the many MANY SHTF stories I have loaded on my Kindle. Nuke or solar flare, they all result in the inevitable EMP. Only the stories and characters change a little. Amazon has plenty of independent and inspired self published authors and lots of SHTF stories can be had (both good and bad) for as little as 99 cents for Kindle. Go check out A. American's survivalist series for one of the best self published authors out there. I have 'em all. (7 books so far) I've never been able to listen to audio books but I do read a lot of 'em.
One of my favorites is Lights Out by David Crawford. I have the dead tree paper version. Also of course One Second After, One Year After, and The Final Day* (* Pre-ordered ) by William R. Forstchen. Then there's Patriots by James Wesley Rawles. I have all these in dead tree versions plus many more.
There's a whole wide wicked world out there just waiting for something to happen so that it can all go to hell in a hand basket. Read all about it.
