Shari Lapena is definitely a favourite author for me. I've given all 3 of her books 5 stars.

Throughout the book I had two different suspects. But then a few chapters later everything changed. In the end I had no suspect. I couldn't think of a reason why any of the guests would murder mulitple people.
The twist at the end shocked me. That character was one I overlooked the most. They seemed to blend into the background the most.

I usually have problems with keeping up with so many POVs but with this is was easy. The writing flowed very easily and each character had a characteristic that helped me not muddle them up.
