I really loved that book for a long time, not b/c of its actual plot or characters, but just the premise of the apocalypse in it. I think I read it in like, idk, mid-late elementary school? And through even through like high school and early college all the time I'd be driving around and thinking, oooh that building would be a useful shelter in an apocalypse, or, about where to get food or w/e, or how I could possible acquire a tank from my dad's work, ha. Eventually I stopped fantasizing about it, but only b/c I eventually started thinking of myself as permanently disabled rather than "temporarily injured and will recover," and realized that I would not make it in the majority of types of apocalypses and I'd prolly just off myself. So now I don't brainstorm apocalypse survival any more.

Anywho, I think it was a few years back when I found out it was based on Objectivism, haha, and it chagrined my dazzle, but not too much, and I was also like, "wow, that main character makes SO MUCH MORE SENSE NOW lol." XD
