Baby, if you don't tell me, how am I going to know?

Book reviews are an important part of an author's life. Good reviews are nice. Glowing reviews are even better, but often the most useful review is one that is critical. An erotica publisher with a successful author (i.e., one that sells a lot of books)isn't likely to pass one of those on for fear of upsetting a writer's delicate ego. Some authors can be very touchy about their work.
Then there are the reviews that never get written. You can infer them by checking sales figures, and usually that's as far as it goes. But once in a while you do something a bit different with your writing and that finally prompts a reader to say something.
Recently, I had my first nonconsensual book published. One reader/acquaintance told me that it was just about perfect from his point of view. Then there was a woman who felt very strongly otherwise. She began by writing that she was a big fan of mine, and had all of my books except one. She went on to say that she really didn't like 'Tanya' at all. She then continued by saying how much she liked all the other books, especially 'Female Prey', 'The Elusive Prey' and 'Augustin's Island', giving each book a 9 out of 10 rating and suggesting what I might add to a future book to bring it up to a 10.
It was all useful information, but it struck me as interesting that she didn't feel moved to express herself until she came across something that she didn't like. I plan to use her advice in the future, and I'm quite happy that she likes most of my books so much, but it would have been both handy and encouraging to know this earlier.
