Alright bub, I get that you're used to MS Word, but before you keep jumping on the MS stuff, lemme ask you something [and I don't mean to be patronizing either]: What do you need in MS Word?
I'm not going to be one of the linux geeks on here and try to preach about "Oh but open so-" no, nonono. If I had it my way I'd be on pages right now and it'd be great.
Short of the short is... Well, theres a lot that is better than MSW and holy shit have I loved it since I ditched word. Theres 3.... Technically 4 programs I tend to use, only 2 that I can even recommend.
Focus Writer
Libre Office
Nano
Abiword.
Focus writer is ingenious in that it has all the functions of MSW with the additive that all the tools and distracting shit goes away, gives you a background to drift into when you need to think, and your text. When I am writing my stuff [ manuals, code notes, bug report, even a story I am working on ] it tends to be in that. If not...
Libre Office. But you know what that is so fuck it.
Abiword is basically office 2003 with 8 tools added on that do what the 2007 tools do with a bit of a twist. Its light, runs on anything, and used to be my go-to till I found FW. Though I still use it and install it to everything. It has reformatting tools built in for MS docs so you can reallign everything, though I would do that on google docs [I'll explain that in a moment].
Nano. Its nano, just a terminal writer. If I can't reformat shit or just need something down I throw it in here and copy it back out or save it.
Since you have a big ass book, here's what I would do.
Go to google docs, open that shit up, let it format it out to what it is, then you can actually translate that to ODT on their site. It has, for the most part, worked for me and I only had one fuck up in doing that but it was my fault anyways (all the spaces poofed).
I hate MSW. Have for quite a while. If you really REALLY need it (egh) go get the latest wine, LATEST, pop open winecfg. set it to XP mode, go to packages, get all the MSV## packages but only the ones with numbers and maybe skip 120, then get the vcomp pachages, then go to graphics and set it to make a desktop and run that space. Make sure you have the space you need too since you can't resize the desktop.
Alternatively, get virtualbox, install windows, run in seemless mode, run it that way.
Again, I hate MSW, and the sooner you jump off that pile of crap the better in my opinion. I'm not even a linux nerd, I just know what works for me.
