About 500-550 words, the feedback the author receives includes a summary to give readers context, together with a concise, unbiased opinion that can be positive, negative, or, most commonly, mixed. With a longer feedback summary, you'll receive additional analysis and a more detailedsummary. Each feedback summary details a general sense of a book’s worth. Feedback also includes specific information about the book's strengths and weaknesses.

Whether positive, negative, a mix of both, you'll always have the choice of keeping the feedback summary private and use it to improve your manuscript. Otherwise, you can publish it and use it to market your book to readers.
