Fight Club follows the experiences of an unnamed protagonist struggling with insomnia. Inspired by his doctor's exasperated remark that insomnia is not suffering, the protagonist finds relief by impersonating a seriously ill person in several support groups. Then he meets a mysterious man named Tyler Durden and establishes an underground fighting club as radical psychotherapy.

In this novel, Chuck Palahniuk offers a dark and provocative look into the depths of the human psyche, delivering a tale that is as unsettling as it is compelling. With biting satire and a unique voice, Fight Club has become a modern classic, exploring themes of identity, consumerism, and the search for meaning in a contemporary world.
