I've not read it properly but a quick skim over various pages shows a good job done with the typesetting.
I have a few - mostly petty - issues that you might want to think about. There are examples of each on page 5 (actual numbered page 5, not the page number the PDF viewer gives it).
1. Hyphens: (Paragraph 3) With things like "out-of-focus" and "lady-of-the-evening" it's more usual to have no space between the words and the hyphens. Having the spaces in there makes it a little confusing and it looks a little like a multiple aside. (And, to be even more petty, I'm not sure that "lady of the evening" needs hyphens. I'd say it was more of an "in quotes" thing as you're really using a euphemism. I could be wrong though.)
2. Quotes: (Paragraphs 4 and 5, for example) I don't know if it's deliberate but you seem to have a mix of quote types. The text starts with an upright double quote but ends with a double inverted comma. It might be an issue with your font or where you imported the text from but it's usual to have the same type of quote at both ends of the text. I doubt the average reader will notice but, for picky people like me, it can be a tiny bit annoying. You can find a good selection of quotes from the "Insert -> Quotes" menu. (You can create some shortcut keys to make them more easily available.)
3. Ellipses: (Last full paragraph) It's more usual to use an ellipsis when the speaker has trailed off without saying any more and to use an em dash to show that the speaker has been interrupted - which is what I think you are doing. (I can't show what I mean here as there's no em dash in this text editor but you can get the em dash from the "Insert -> Character" menu.)
None of the stuff I've mentioned above is particularly important to the average reader. Most people probably won't notice but if you're going to get into typography in a more hardcore way then there are all sorts of little rules and guidelines that you would benefit from learning.
If you - or anyone else reading this - want to learn more about this sort of thing I can thoroughly recommend a book called "New Hart's Rules" by Oxford University Press (ISBN: 0-19-861041-6). When I got my copy in 2005 (there's probably a newer edition by now) it cost less than £13 and it's got more information and tips on preparing copy for publication than you can shake a stick at. It's not just for British publications either but it only really covers languages that share similarities with English (US conventions are covered pretty extensively).
Anyway, your book looks great. Feel free to ignore what I've said above, most people won't be as picky as me.
