The novel shifts perspectives between Cassie, Ringer, and others, each grappling with the fundamental question of the series: who can you trust? Yancey's YA sci-fi maintains the brutal stakes of the first book, with significant violence, deaths of teen characters, and psychological trauma throughout. A suicide attempt is depicted in one storyline.
