If any of you guys can get past the style that manga is read (Japanese-style graphic novels that read from right to left, though translated), there's a really good one that I picked up today, called "Metro Survive". It revolves around Shogo Mishima, a maintenance worker for a shopping/business complex. He and other passengers of an underground subway get trapped when a large earthquake occurs. Taking a lot of cues from movies like "Daylight" (IMHO), Mishima uses his maintenance and engineering training to try to find ways out of the subway for himself and the others.

At one point he remembers maintenance tunnels run under some large escalators for easy repairs, and it's one of these that he opens to get people past a wall of rubble. He also has the foresight (along with the train conductor) to tell people to avoid the "third rail", and also has knowledge of structural integrity, archetecture, etc., which show up as blueprints he is thinking of in his brain. Pretty cool stuff here which turns Mishima from your average blue-collar worker into a hero at some points.

Also the book goes over a lot of group dynamics, food and water rationing, careless actions of other survivors which make things tough, selfish people looking out only for themselves, etc..

Suggested reading age 15 and older, according to the book. Link here (and of course I'm in no way affiliated with these people):
