Survivors : a novel of the coming collapse, by James Rawles

Whacked out far right near future apocalyptic thing. This had so many plotlines, and so many different characters trying to survive "the crunch" that it was hard to follow, but the main point was definitely buy guns (many), ammo (as much as possible), and hoard metals. In this particular vision of worldwide upheaval, US inflation lead to Weimar-era style worthless paper, and riots and such quickly followed. The rest was pretty standard Ayn Rand-leaning survival stuff, but it did have an interesting and exciting recipe for home-made molotov cocktails, which was a nice touch!

1 pint jar
thickened gasoline- thicken pure gasoline with styrofoam until it is thick like molassas
1/2 cup battery acid

put both in pint jar, seal, and wash carefully.

put 2 rubber bands around jar.

soak sheets of paper in potassium chloride solution, let dry, cut into strips.

put strip of paper through rubber bands.

when ready to use, shake jar and throw- supposedly, once the mixture inside touches the paper, BOOM.

(I am not- repeat- NOT saying anyone should try this or that it works - just that it was highly unusual to find recipes for homemade weaponry in a terrible novel.)
