It was supposed to be the trip they would talk about for years. Instead, it became the day their lives ended or so they thought. When a strange yellow smoke swallows their bus, a group of students wake up in a city that should not exist. The streets are abandoned. Skyscrapers lie in ruins. Their phones are dead. And there is no way back. Then they discover the skeletons. Someone or something has been here before them. As fear turns to desperation, Dorian begins to show abilities that no ordinary student should possess. And Aria starts to realize that their arrival in this ruined city may not have been an accident. The city is watching them. The smoke is waiting. And the longer they search for a way home, the more they discover that getting out might be impossible. Because this isn't just a school trip anymore. It's a journey with no end.
