 Ellis began working on what would become Imperial Bedrooms during the development of his 2005 novel , Lunar Park . As with his previous works , Imperial Bedrooms depicts scenes of sex , extreme violence and hedonism in a minimalist style devoid of emotion . Some commentators have noted however that unlike previous works , Imperial Bedrooms employs more of the conventional devices of popular fiction . Reviews were mixed and frequently polarized . Some reviewers felt the novel was a successful return to themes explored in Less Than Zero , Lunar Park and American Psycho ( 1991 ) , while others derided it as " boring " or self @-@ indulgent .
