Had you taken just 30-seconds to post that in a Google search box, you'd have found tons of audio book review sites.

Since each has separate categories of books, you best bet is to visit each of them, and see what areas they cover.

Start here: http://www.english-test.net/shop/ent...dio-books.html

There are over 400,000 such sites listed. If it's important, it's worth taking the time to research them!

For the most part, you'll find that reviews come from folks that have already purchased your book. Your best bet might be to ask several well known marketers to review your product.
