I’m a fan of that book too - though hoping I never need it! On a tangential theme, another one I read and liked at the same time was The World Without Us - all about what would happen to the cities and infrastructure if all humans suddenly vanished overnight. Kind of depressing but there’s a lot of interesting and non obvious stuff in there
