First published in 2013, Shift is a dystopian fiction novel written by Hugh Howey. It is both the prequel and sequel to the first book in the science fiction trilogy known as "Silo." This novel followed the success of Wool, which initially gained popularity through its serialized format on the internet. It introduces new characters and provides insights into the larger conspiracy surrounding the silos.
The narrative is divided into two main storylines. One storyline takes place in the distant past revealing the origins of the silos and the reasons for their construction. It delves into the political machinations, technological advancements, and the complex motives of the individuals involved in the creation of the silo system. The second storyline is set in the present continuing the story from Wool. It follows a new set of characters as they uncover the secrets of the silos and struggle to survive within this confined underground world. As they navigate the treacherous landscape of power struggles and corruption, they gradually piece together the truth about the silos and their purpose.
Throughout the novel, Howey weaves together intricate plot twists while exploring themes such as the consequences of deception and the ethical implications of sacrifice. The Guardian stated, “Whether or not Howey believes in the details of his story, the anxiety, claustrophobia, and lethargy he conjures are heartfelt and convincing.” The success of the series led to further books such as the concluding installment Dust and adaptations into other forms of media.
