I agree with weasel. The type of book, its length, and the amount of literary devices it utilizes can all affect your report. For instance, if you're doing a report on a Captain Underpants short story, your report is likely going to be a paragraph of poop joke. If you're doing a report on a more in depth novel such as Atlas Shrugged (extremely good, a life changer also, granted you can bare to read over 1000 pages and over 645,000 words), your essay will be well over 10 pages, unless of course your a college professor or a Democratic politician, in that case you would have burned the boor at around page 157.
Was this any help?
