Is there something in the work that appeals to you, moves you, frustrates you? Find that focus and then begin the research process. Depending on your choice, there could be a number of themes. Begin to see what’s out there using either the library online databases or print material like books or periodicals from the local library. You may not use general internet sources.
Develop points related to your focus or angle. Think about your angle: what approach are you going to take?
Were there parts of your novel that you relate to on a personal level? Were there characters that you have a particularly strong feeling about? What theme do you see?
There are many other approaches you can take. Just make sure it’s your own approach. Regurgitating things you read from websites is a bad idea. Taking movies you’ve watched, things you’ve read, or experiences you’ve had and finding relationships to the novel–themes, ideas, connections–I’m interested in any of that.
