Bestselling author Jonathan Lethem delivers a hilarious novel about love, art, and what it's like to be young in Los Angeles. Lucinda Hoekke's daytime gig as a telephone operator at the Complaint Line—an art gallery's high-minded installation piece—is about as exciting as listening to dead air. Her real passion is playing bass in her forever struggling, forever unnamed band. But recently a frequent caller, the Complainer, as Lucinda dubs him, has captivated her with his philosophical musings. When Lucinda's band begins to incorporate the Complainer's catchy, existential phrases into their song lyrics, they are suddenly on the cusp of their big break. There is only one problem: the Complainer wants in.
