A dystopian, murder, who-done-it mystery set in the not-so-distant-future

The Last Murder at the End of the World is the first book I've read by this author, so I look forward to reading his previous book now that I've read this one! It is a dystopian, murder, who-done-it mystery set in the not-so-distant-future and deals with such issues as human greed and ingenuity, artificial intelligence, protecting our environment, and what defines humanity. It starts slowly, but builds as the various characters reveal secrets in their pasts, as observed by the AI who narrates the book and a countdown begins to the end of human existence. I do wish that there had been a bit more explanation of the fog/insects (was it man/lab made? where did it come from?) and some more glimpses of life before the fog for each character, to get to know them better. I appreciated the ending had a hopeful conclusion. This would make a wonderful movie or mini-series.
