In the audaciously metafictional 'Lunar Park,' Bret Easton Ellis weaves a tale of redemption and terror, mixing the true with the unimaginable. Ellis, the protagonist sharing the author's name, is a successful novelist known for his excessive lifestyle. With a new chance at life, he finds sobriety and starts a family in the suburbs. Yet tranquil domesticity spirals into unsettling horror as his past transgressions and psychological demons resurface. When a Halloween party invites a cascade of chilling events, Ellis confronts not only violent disturbances in his home but also his link to a chain of gruesome murders. Questioning reality and battling addiction, he struggles to protect his family against the shadow presently haunting them—a threat from either external forces or his own mind.
