Unlike others (mostly on Goodreads) who didn’t like the book, I actually liked the fact that we got glimpses/novellas of different times - it meant we understood the people a little better as we understood where they came from. 

I had recently read The Ruins and Eden so I wasn’t looking for a plant horror book, which is good because this isn’t one. (And seems to be another reason people didn’t like it) 

Also, some people seemed to be bored by the plant science - I actually loved it and I think having read it as an audiobook really helped.
