Max Light is an imaginary publisher, who publishes the books of Sarah Smith and other people.
He's Max Headroom's cousin.
He looks like Robert Downey, Jr., in Wonder Boys.
He's a sock puppet with serious drug issues.
His work is actually done by his assistant, Keisha McDonald. Like all assistants in publishing houses, they're the person you actually want to know.
The books are real, and so is Sarah's agent.
