Three teenagers. Two weeks. One mystery. As Victoria "Tori" Benjamin, Autumn Henderson, and MaKayla Johnson board the S. S. Oceanus VI for a two weeks long cruise, they expect the usuals. Relaxation, exploration and fun are at the top of their agendas. However, on the second day, an unexpected storm hits and forces them to pull in to the nearest harbor: Obsidian Bay of the Sterling Isles. Because of some needed repairs, Oceanus must stay docked for over a week so the ordered supplies can arrive, forcing the girls to find a replacement for the adventure they had in mind. But this island is stranger than they think; it won't show up on any map and nothing about it was documented. But disappearing passengers and reoccurring murders immediately catch their attention- for if they fail to find the kidnapper and murderer, they will be next.
