This was a different "end of the world" synopsis. No zombies, pandemic, or virus. You can guess- it is a fog. The  children grow up as young adults in this book, which I found wonderful! A refreshing read. You will see the endurance of the human spirit and can easily see what could happen in these circumstances. Not the "fog", but if any children were left to their own devises for a long period of time. Several people have made negative statements about a kid of 16 pairing with another, about age 27 years old. That would not be uncommon in this type of setting. The amount of people in this story are limited. Also, sexual desires often takes precedence over what would be considered normal. I never make comments of editing. I know any author is doing the best he can afford at the time.
