This is a revenge story that makes it very hard to empathize with the main characters. It's a twisty thriller mixed with a bit of murder mystery. Chloe, Annabel, Tanya, and Esther were friends through secondary school (high school) but have somewhat drifted apart through their adulthood. 10 years later, they receive an invite from Poppy Greer, a woman they bullied in high school, to her bachelorette party on a remote island in the Bahamas. They all decide to go, even if they aren't sure of Poppy's intentions and why she is inviting them. As they arrive, secrets come out that all of them have shared and they all have to face them on a remote island with no outside communication.

We do get flashbacks through Poppy's journal to see what happened in the past 10 years ago. This helps provide context to the situation and exactly what these women did to her. The main point of views switch between the four characters. One thing is certain, you don't like ANY of the main characters. By the end of the book, they have no redeeming qualities and they did some pretty awful stuff. 

I would say the action picks up pretty quickly and it's a fast paced story. There is a ton of cattiness that emerges from the beginning and just drama that keeps you turning the pages. Halfway through the book, it's pretty evident what the big reveal is and I feel like a lot of the hinting was pretty obvious. Despite that, I just enjoyed the chaos that was this book. It's nothing revolutionary, but very enjoyable and a fast thriller to read.
