Ive thought a lot about this. This story is very flat when it comes to the emotions of the event itself. Partly, I guess, due to the fact that it starts with Javeen who is tasked with trying to shield Kirsten from the horror as best he can. But I think, traditionally, the emotions and feel of the event itself is a key component to good post apoc. Probably not as important as the psychological effects of living post-event but still important.
