Pamela, the first piece of advice I can give you is find out how many advanced reading copies you can get from the publisher. Then start compiling a list of authors and reviewers you'd like to read the book and give you a review. For authors, send them a short note ahead of time giving them a brief paragraph or 2 about the book and asking them if they'd like to read it and provide a review. (by the way, if you queried me with a request, I'd love to read it and give you a review. )

For reviewers, everyone has different submission policies, so follow them carefully. Some want the book 4 months before publication, some want it with a whole package of info, so be prepared.

You can find some great reviewers at http://freereads.topcities.com/bookreview.html

As for advanced marketing, here is a great link for what to do up to a year before your book comes out.
