What is the author's style in Less than Zero by Bret Easton Ellis?

This story is narrated from the first-person point of view, meaning that the story is narrated from Clay's perspective and is limited to his thoughts and impressions of the action around him. Many critics have noted that Clay maintains a detached sense of irony in his narrative perspective. This detached tone is in part indicative of Clay's nearly constant drug use, and in part an expression of his complete sense of alienation from his own feelings, as well as from any real emotional contact with his friends and family.
