I listened to this one and although some of the narration was a bit annoying at times, it was an easy one to have on whilst doing other things and certainly kept my interest.

This was definitely more mystery than thriller so it didn't quite have that edge of your seat enticement. However there was still plenty to unpick throughout and a few clever red herrings. 

The author has an engaging writing style that gave a good flow to the narrative. The multiple perspective chapters provided the pacing and further insight into each character.

I liked the whole ameteur sleuth concept of two sleep deprived protagonists brought together through a shared sighting. 

Unfortunately, I didn't particularly like any of the main characters so found it hard to gel with them. They sometimes came across as stereotypical which meant the depth wasn't quite there. However, their dialogue and interactions both with each other and supporting characters were well written and believable. 

There were definitely some plot holes that took away from the plausibility of the book as a whole. Certain things just didn't make sense for a given scenario or character and this was disappointing. 

There was a whole back story of Tim's that I think was supposed to bring the emotional element, but to me, it felt like a plot filler and not something I was emotionally invested in. 

Overall, a good 'pass the time' book but nothing particularly memorable.
