Jane is a character in Orson Scott Card's four-part Ender's Game series. She first appears in Speaker For The Dead.
Jane is an ancient, unique lifeform who lives essentially in the computer network connections between planets. Initially, she is known only to Ender, the protagonist of the series. Jane has complete control over the entire computer network on all the Hundred Worlds, and can do anything Ender asks related to this network, thus giving him a great deal of subtle power.
