As an author, I know how hard (and time consuming) it is to seek out those who will review your work. We hope that anyone who ever reads our work, will post a review at least on a site that they've purchased the book. It doesn't happen that way. Too many times authors' reviews are not in line with their sales.
As a book reviewer, I own and operate Amy's Bookshelf Reviews. I have been officially reviewing and posting my reviews since 2014. Now, I am a reviewer who will read pretty much anything, and review it, from any author of any genre. Now, I do have rules and policies, and they must be followed. Any author looking for a review from me can go to my "request" page of Amy's Bookshelf Reviews.
Now, if I review your work, it is just one review of your title (I'll read more of your titles, but still that is only one review for your title). It is not always easy to know where to go to look for reviews.
So, here is a few recommendations. Look for Book Reviewer Directories. You can do an internet search and see what comes up.
I am currently listed on a few directories, so here are those links.
Other options for finding a book reviewer is also to look at sites such as Goodreads.com or Amazon.com, look at reviews that were written, and if you see a review of a book similar in your genre, click on the name of the reviewer. If they do it frequently, they will have a review profile and be ranked. (My goal is to make it on Vine, amazon's leading reviewers). Here is my reviewer profile on Amazon.
What I recommend is that you carefully look at the reviewers, what genre they read, and how to request a review. Not everyone may still be open to submissions or still be in service.
Also, before you request a review, see what their policy is on review ratings, and also read some reviews that they have written. Personally, I don't give anyone under a three-star review. If I read (or try to read something) that is less than 3-star quality, I send it back to the author, and don't write the review. The author has the option of submitting it again after it's been updated.
I hope this helps, but also, and I recommend this, if you are also a reader (and an author should be a reader), post a review. Do for other authors what you want readers to do for you.
