Hi jhanbackjr,
I looked into it. Seems that the plugin pulls average rating from WORK (which is based on all editions) and also fills stars based on that, while ratings-count is based on a single ISBN. There are 2 ratings_count in API, one in Work en one in Book. On line 302 (stars&ratings) in goodreviews functions.php i changed $Result->book->ratings_count into $Result->book->work->ratings_count. Now it gives the ratings_count (WORK) from all editions.
Thought I’d share the info for next revisions.
