In a post-apocalyptic world a dangerous fog collapsed society 90 years ago. Life as we know it now no longer exists. If the fog didn’t kill you murderers, cannibals or diseases would.
On a distant island scientists - Niema, Hephaestus and Thea - have created a society with strict rules that allow them to survive the fog. A village of only 122 where everyone knows not to question the rules and the secret bruises that appear on them at night. Emory is the only one who dares to question the inconsistency and rules set by Niema.
Niema knows she needs to commit a murder to help humanity survive but will she be able to complete her task before it is too late? But when the villagers find Niema brutally murdered they only have 92 hours to solve more than one crime.

I was intrigued by the description of this book but I struggled to stay with it until the end. I am not sure if it was the narrator who seemed to have a flat tone, or if it was the never ending plot. I felt it was too similar to The Island of Doctor Moreau mixed with West World but not in a compelling way. I do feel that this could have been a great plot if it had more outside influence, or an unpredictable twist. I also would have loved to see more of their “night time duties” incorporated throughout the 1st half of the book.
