Set in a disturbing near-future Britain, Divided Kingdom imagines a society that has been radically reorganized according to personality types. Citizens are assigned to separate regions based on their dominant temperament, with the aim of creating a more harmonious and efficient nation. Thomas Parry, an ordinary man struggling to adapt to the system, embarks on a journey across the divided country that forces him to confront questions of identity, freedom, conformity, and human connection. As he uncovers the consequences of this social experiment, he begins to question the foundations of the society in which he lives.
