My supervisor has been writing a book (for many years now) and he has a heavily customized LaTeX style that actually works quite well for his book. He has a lot of special needs for formatting so none of the default styles really worked for him. It's actually a pretty well done dynamics textbook. I've been looking forward to the actual final published text.

You should ask him if he's considered publishing the styles under a Free/open license. Even if parts of it is very specialized, I'd surprised if it couldn't work as an interesting starting point for other projects.

Next time I talk to him, I'll see about it. I don't talk to him that often now that I've finished my PhD.
