Interesting discussion but I would like to point out that I did not say that Ark was a "post-apocalyptic" book. I said it was an "apocalyptic" book. So to make sure that someone does not read the book under false pretenses ..... The starting point of the book is that the earth has discovered a monstrous asteroid on a course that will obliterate the planet in decades. The earth pulls together to move out (this small book does not go into any detail about this) it tells the story of a young woman who intends to die rather than escape.
