The novel follows the life of Lucian Taylor, a young writer living in London at the turn of the 20th century. Lucian is a dreamer and an idealist, seeking artistic fulfillment and spiritual transcendence. However, he is constantly plagued by poverty, loneliness, and a sense of alienation from the mundane world around him.

As Lucian delves deeper into his artistic pursuits, he becomes increasingly obsessed with his own imagination and the mysterious forces that seem to guide his creative vision. His dreams and fantasies blur the line between reality and illusion, leading him into a surreal and hallucinatory journey through the landscapes of his mind.

It has been praised for its exploration of the darker aspects of human nature and its haunting evocation of the mysteries that lie beyond the boundaries of everyday perception.
