As a writer, of course I believe in book reviews. Not all readers see the value in them. Why would it help you as a reader to take your time, which most of us agree there is never enough of, to review a book? If you are interested in the quality of the books you read, you should take the time to post a review. Most writers read each and every review that they are aware of. I know I do. I want to be the best writer I can be and I think most writers share this view. If you love something in a book and want to see that or even more of that in future books, say so in a review. Does something irritate you about the writing style of an author you love? Let them know. Maybe it is something they never noticed because no one ever pointed it out. I have been very lucky to get suggestions from my writer’s group and readers who have read my first book. I want to grow and improve and I do make changes because while I do write for myself, I also write for readers. A storyteller with no audience isn’t a storyteller at all.
