The novel was published and released by Simon & Schuster on October 2, 2007, and is a companion book to the Uglies series. However, Extras differs from its predecessors in that its protagonist is fifteen-year-old Aya Fuse, not earlier protagonist Tally Youngblood. Despite the fact that Youngblood is not the main character, she still appears in the book's later chapters in a major role."@en . "417"^^ . "Extras"@en . . "148318216" . "ISBN 1-84738-126-X" .
