Literature is a genre literal and appears as a young woman in a dark suite. She is said to hold others in contempt. She was called upon by Kevin; who was under the influence of Writer's Block. However, he still found even with the genres here, that they were boring. Bigby, Snow, Gary, and Mister Revise; along with the Page Sisters, had come to stop him from doing further damage to reality. Kevin sent the Genres, including Literature to guard his house and fight off the others.
She took great interest in the fight, as did Horror, in the battle when they heard Mr. Revise was near. She held a grudge against him for encouraging a ban on the book Ulysses and hoped to kill him for it. Bigby, who had been put through much humiliation and transformed into a girl to further it, lost his patience. While Robin, Priscilla, and Hillary fought off the others, he snuck around trees and attacked all the Genres.
While none of the others took Bigby seriously due to his appearance; that would be a mistake as Bigby would show no mercy and kill Literature and the rest of the Genres. For the moment, after defeating Kevin, Literature and the rest of the Genres had apparently recovered. Or it meant they were resurrected by Kevin or simply replaced. They were all sent into a new world where Kevin could do what he want and leave the mundy world alone.
