Excellent book, with good characters, tough decisions, and practical advice. Worth the read, even just to provoke some questions in your brain.
And I liked the way the characters were ordinary joes, who weren't prepared and waiting like in *some* other books/stories. They had to improvise, think on their feet, scrounge, etc, not draw from stores what they needed.
I tried to read some of the short stories on Frugal Squirrel, but it just seemed like everyone of them started out with "So and so grabbed their Springfield Armory M1A National Match .308 rifle...yada yada yada going on to describe a $5K loadout out of their car trunk along with several hundred dollars of supplies in their bug out bag, then hiked 20 miles out of the city to their remote, well stocked cabin in the hills, where they lived from then on, shooting the various sundry intruders, etc. Few were very good or original. "Lights Out" was one that was actually great.
