You've just completed your manuscript! Hooray! Give yourself a big pat on the back for seeing your dream through to completion.
Next step, get a professional evaluation of your work before submitting it to a literary agent.
Yes, it is okay to let your friends and family read the manuscript. They can cheer you on and keep your spirits up as you take the next step. They cannot give your work the honest and objective manuscript critique that it needs.
What you will receive from me is a page-by-page evaluation of what is working and what is not working in your story.
For fiction and memoir, that means an assessment of characterization, plot, dialogue, setting, pace, tone and description.
For other types of nonfiction, it means assessment of the elements that might affect the salability of your manuscript such as coherence, consistency, organization and structure.
