Thanks for your response but I'm still a bit confused about your answer to my 3rd question. I renamed the file to .zip and see a bunch of .html files in one of the folders that contain the text of the novel, however it opens with my browser and I'm unable to change any of the text. Can you provide a few more steps as to what I need to do next?
Can you also explain how I would go about doing that and explaining what you mean by importing the .opf file into Calibre? Do I just import the .opf file and nothing else into Calibre?
