Have you try to get a PDF of the word document, using MS Word? I Recommend once finished the book, have different copy of each page in PDF and place it where you want. Hope this help.
The problem with the PDF’s is that they are NOT to read on mobile phone, due to the size of the screen, also if you could enlarge it, have to be spend too much time trying to read it.
Have you consider using RW with a responsive template. Every time you published it could be read in all devices, from full size to phones, no matter the brand or size. That means that you don’t have to worry about size, and spend all your effort in writing. Expand it and it will work always.
Had a page with past issues, so readers can check recent or old ones. Hope this help.
Voyager Pro looks promising.
It is a responsive theme with
Sticky navigation bar, ExtraContent Areas, Override Site Banner.
