Hi and welcome Chasmira!
Ebook reviewers are tough to come by as most in the tradtional industry still are lukewarm to ebooks at best. Reviewers for print books are harder and harder to snag too.
One suggestion I do have for you is to see if you can find blogs related to your audience or storyline. First follow and participate and then ask for a review by contacting the blogger personally. Some say that bloggers now set the pace in media vs more mainstream outlets so this is becoming a more common strategy.
If you're on Facebook/MySpace, you might also try to reach out that way.
Hope that helps.
