First of all, forums are probably one of the best ways to get your book reviewed. Find out which forums are related to the topic of your book and introduce yourself to the forums. Interact with the members of the forum and quote your book if possible when answering a "thread." Obviously, you will want to have a "hub" and a blog about the topic of your book, so that you can establish yourslef as an authority. Join Squidoo and create a lens there about the topic of your book and leave a link to your book and where to purchase it. How big is the book? If it's really big, you can post excerpts from your book to entice readers. I wrote a small book (52 pages) which can be downloaded from my site. However, many people prefer to have a hard copy. However, if it's downloadable, the reader can peruse it and you can get their email before they download it and ask for a testimonial in exchange. After becoming established, you can withdraw this free download and sell it. It all depends on what your topic is about and how established you are as an author. If your topic is a "hot" one, you may not even have to give it away. In the attached video, is Arielle Ford, publisher and literary agen. Possibly she is your answer to fame.
