3.5 stars
A highly enjoyable popcorn thriller but I found the characters a little empty. As in, none of them really stood out or jumped off the page.
The format was bad with numbers on every line and at the end of every sentence (assuming it was the ARC upload to netgalley) so reading was a bit jarring.
Overall though, I enjoyed it but it's one not to take too seriously. A locked room/island mystery with an ending I didn't really see coming but not overly shocking.
Also ... was the production coming in on it or were they all just really bad at their jobs?
