The novel has been compared to other young adult books such as The Hunger Games and The Maze Runner because of its similar themes and target audience. In particular, the novel explores the themes common to young adult fiction, such as adult authority and the transition from childhood to maturity, as well as broader motifs, such as the place of violence and social structures within a post-apocalyptic society. Its major plot device, the division of society into personality types, is one used in other science fiction works. Beyond its literary context, Roth's open declaration of her religion as a Christian has brought commentary from Christian communities both endorsing and challenging the novel.
