Bret Easton Ellis is an American author known for his provocative and controversial fiction exploring the dark underbelly of contemporary American life. He burst onto the literary scene at age 21 with "Less Than Zero" (1985), a nihilistic portrait of wealthy Los Angeles youth. His most notorious work, "American Psycho" (1991), is a savage satire of 1980s consumerism and violence that sparked widespread controversy upon publication. Ellis's other novels include "The Rules of Attraction," "Glamorama," and "Lunar Park." His spare, detached prose style and unflinching examinations of excess, superficiality, and moral vacancy have made him one of the most distinctive and divisive voices in American literature.
