Book character(s) you'd like to see with their own Twitter page
Ooh, interesting. I would say Enjolras (Les Miserables) - he could try to gain new followers to join him at the barricades. The Greyfriar (Vampire Empire Trilogy) - he could update us on his cats. And finally Loki (Gospel of Loki) - he'd provide daily quips and sarcastic commentary.
