I read this post and found it interesting. As a reviewer myself, I can understand her point of view. It is always wise to be professional in your communication and remember that we review because we love to read. It’s our love for a good book that has us volunteering our time to complete book reviews.
As much as we would like to consider and read the majority of request that comes through our inbox, please keep in mind that sometimes it’s just a matter of timing, the book isn’t a good fit at the present time, and prior commitments.
