When her sister, famous influencer Peach Winter, is invited to an all-expenses paid trip to a luxurious art and music festival for influencers on a private island in the Caribbean, Plum intercepts the invite and asks her two best friends Antonia and Marlowe to come along to the fest with her. When they get to the island, it's not anything like it seemed in the invite. The island is run-down, creepy, and there doesn't even seem to be a festival-- it's just seven other quasi-celebrities and influencers, and none of the glitz and glamor she expected. Then people start to die.... Someone has a vendetta against every person on the island, and no one is supposed to leave the island alive. -- adapted from jacket
