Find three readers that you can trust to give you honest feedback. Ask these people if they will read the manuscript and give you both positive and negative feedback about the story itself or the research. If this is fiction, find one person who reads this genre of fiction and find two other readers who don't usually read this genre. If this is not fiction, find one person who understands the topic fully and find two others who are not as familiar with the topic - but people who are familiar with this type of scholarly writing or inspirational writing. [Suggestions are available on this site to help the readers provide you with meaningful feedback.]
