I've been developing a 1 prim book (nearly finished) - it preloads textures, it opens/closes, next and previous page, next previous chapter and I'm just about to start working on a few plugins so each page can be a vender or notecard giver.
I'm not a programmer - basically I flow charted ,or mindmap, what I want and cut/paste from other script examples (wiki etc) and ask silly questions on this forum.
I feel Lidens have become too greedy so I'm pulling out of SL and going elsewhere. All the work I've done so far has been in the Beta grid.
If anyone would like to run with this project - IM me in the next couple of days and I'll arrange to get the textures, script and prims etc. to you.
The book works on texture grid that allows 18, 8 or 2 pages to be loaded onto a single texture (depends on the resolution you require) - As it stands there are examples of the 18 page textures to work with plus covers texture and configuration notecards etc.
If I can help any further I sure we can arrange a Facebook or other contact.
Thanks for all the support and friendship shown in this forum and good luck with all your projects.
