Book Reports / Thesis for Paradise Lost - original thesis needed [6]

Thanks for your help everyone I have came to the concept that i am going to do it on who Milton has as the hero in Paradise Lost, is it God or the devil. I have came across the most information on this area. I am now just having problems with how to start it and what exactly I need to talk about. I am afraid of using websites that are not reliable and seeing that i do not have access to a library this time I need something that I can trust. Does anyone know of trusted sites on Paradise Lost or other perspectives on it?
