The pace of this book was too leisurely for me, and there was practically no literary value to sustain that leisurely pace, and no characters you care about. 
 There was no real sense of danger, at around page 90, you think: oh yeah, shit's gonna go down...oh wait no..it doesn't. And on and on. 
 Comparison to The Road: 
 Survivors wandering about the ruins of civilisation relatively peacefully as opposed to packs of marauding cannibals. 
 In this story, only Man is killed off in large numbers - other species and plants survive so it is possible to live off the land (or canned food - of which there seems to be an unlimited amount) without fighting for every last scrap. 
 Everything is so safe - childbirth problems? Immunity? Everything seems too pat, everyone seems to be too lucky. 
 Maybe something happens later, but I wouldn't know - too boring, didn't read.
