My MC, a misanthropic sociopath who ends up worshiping Iblis, getting horns tattooed on his forehead, and is either plagued by a demon or vivid hallucinations, is reading a book within my book called Eclipse. I'm starting to wonder if it's getting too long. It's a first person book written by a fictional Egyptian scholar from the viewpoint of Iblis, so it is pertinent, and the ending will be especially, but right now I'm describing the Islamic Apocalypse, and it's 11,000 words out of my book's total of 41,000 . . . and I'm not really close to done it. Should I break it up into sections, so that it's the text of the book, then my MC's adventures, then the book again? Do you guys think I should omit the less interesting parts, or just go through until the end, and shorten the parts that aren't that important? It's full of interesting stuff (Jesus, Mahdi, False Messiah, warfare, Gog and Magog, mythical beasts, etc.), but I'm wondering if it's just getting too long now.
