Annabel, Esther, Tanya, and Chloe were best friends as children, though life hasn't come out quite how they thought. When their former friend Poppy invited them to a remote island for her bachelorette party, they are stunned to see how gorgeous and successful she's become. With lavish accommodations but no cell service, their tropical vacation quickly turns into a nightmare where past secrets refuse to stay buried.

Just from the publisher's description, you know She Started It is going to be over-the-top, yet Gilbert takes the drama to a level too hard to swallow even for a guilty pleasure revenge thriller. Flashbacks quickly reveal that the four mean girls made Poppy's life a living hell in high school, making the whole premise of begin invited as bridesmaids (and them accepting) impossible to swallow. Add in completely unlikeable characters with unrealistic motives and a big twist that I guessed early on, and I can only recommend She Started It to someone who wants a shallow but fast-paced summer read.
