I found this post on LinkedIn about software that finds names and email addys of Amazon reviewers who wrote four- and five-star critiques of books that are similar to the software users' books. The software users can then ask those reviewers to consider an Amazon critique of their books. I haven't used the software, plus you have to be a member of the Author Marketing Club. But hunting down four- and five-star reviewers of similar genre books seems like a good idea for promoting the anthology. Here are the links to the posts:
