James Rawles - Patriots explores a similar collapse through a different lens (prepper/silver). At times it gets caught up in prepper details/instructions but is a great read if you enjoy that sort of thing.

I've read it. A little far fetched and the main characters are full fledged preppers who have invested years and hundreds of thousands into preparedness. One second after is more around common family reaction to an "apocalypse". both are entertaining though.
