Suzannah - there is no one sized fits all answers. I think your best path would be to read a book or two and see where your topic fits as far as approaches go. For example my book contract is something called "work for hire." A publisher approached me about doing one volume out of a series because it's an area I have expertise on. I got paid a lump sum payment and won't get royalties or own copyright - which is fine, it wasn't my idea or format. However - when I want to write another book, my platform will be expanded because I'll have the experience of promoting this title.

As I said this really varies. Some give you advances against royalties. You need to understand what everything means though and know what other similar titles earned.

Everyone has their own method. Go look at similar books and see what worked for them.
