How to do (Can I do) Indexes with teasers.

Is there a module that will create something like this (ignore the colours)
http://www.onebit.ca/cricket/#botp

I'm thinking of making a Drupal book for my fanfiction; one of the primary links of the site would be to the root page for that book. Then the trilogies, books, and chapters, would be children, grandchildren,...

The first bit of each story / chapter would be the teaser. (Possibly blank.)

The questions are:

1. How do I (automatically) include the teasers in the index?

2. How do I list two or three levels in each, rather than one or all? So that if you're on the top level, you see levels 2 and 3. If you're on level 2, you see 3 and 4.

3. (Icing on the cake) How do I include teasers for two levels and just links for the third? So you always have an idea what's below you, but not all the details.

Alternatively, if I go with a static page for the index (and update it by hand, which is something I was hoping to avoid),

4. How do I make it so that they can't get to the automatically generated index page? I just know they will, and then wonder why they don't see the teasers.

If there's something else that would work better than books, I'm open to that as well.

Thanks!
