Everyone wants reviews for their books. I know I do. So how do you find them?
Check out author pages, that's how. Authors will always post their reviews on their websites - it's only natural. If you're looking for Romance Reviewers - go to the second page of this blog (click above, or in the Reviews button in the right hand bar) and you'll find some you can contact.
Visit the reviewers' sites and make sure they take your type of book: some don't take e-books, others don't want self-published and some don't want to see books that haven't been released yet. Check out their genres too.
Review submissions is not unlike the original book submission process: check out the sites, be professional, submit only what they ask for. And have a synopsis or blurb handy because they normally want one.
