Ruth Ware is such a great thriller writer and this one did not disappoint. This is a modern take on the locked room mystery trope. Using reality tv as a backdrop and social media elements to make the characters relatable, the author takes a trope we all know and gives it fresh life. With "And Then There Were None", "Lord of the Flies", and "Animal Farm" vibes throughout, Ware weaves together a story that keeps you guessing until the very end.
