Member Area Book Script?

Hello,

I've written an ebook. While I've considered going with PDF, I've decided that I want to include it in my website as a member area which I will most likely manage with Amember, but my options are open at this point.

I have a few very simple needs and just a few little extras.

#1) All I really require is the ability to add a page and allow for you usual book-style navigation. In many ways, this "page" will function as an article. It should be setup so that the articles flow in a specific chronological order. I really like how the documentation looks at http://codex.wordpress.org/Main_Page where they apparently use MediaWiki. Unfortunately, my initial experiences with MediaWiki have been horrible and I have a feeling I could write my own PHP script for this faster than using MediaWiki.

#2) I require SEO friendly URLs and code.

#3) While this will be a paid member area only book, I'd like to display a teaser / mini-sales page for non-members specific to each page to take advantage of the search engine rankings my site has built up. For example, Wordpress has its "the_excerpt" which I could basically say "Looking for answers on X, read all about it when you purchase" or whatever on the "X" page..

Off the top of my head, that's all I require. I really want to use Wordpress for this as I know it would be great for #2 and #3 right out of the box. It's just going to take some work to get #1 to function correctly. I know MediaWiki can deliver #1 (not sure about #2 or #3) but I really don't want to deal with it.

Any thoughts? I'm open to just about anything.
