Bret Ellis, the narrator of Lunar Park, is a writer whose first novel Less Than Zero catapulted him to international stardom while he was still in college. In the years that followed, he found himself adrift in a world of wealth, drugs, and fame, as well as dealing with the unexpected death of his abusive father. After a decade of decadence, a chance for salvation arrives; the chance to reconnect with an actress he was once involved with, and their son. But almost immediately his new life is threatened by a freak sequence of events and a bizarre series of murders that all seem to connect to Elliss past.
