What advice can you give someone who keeps getting rejected by literary agents? What should they do? Any writing advice to give?
Tough question without more information -- but I have many projects that haven't found publishers, and most authors I know are in the same position. What do we do? Write a different book. That's tough to hear but it is true. Most working writers are embarking on the new book as the old one is out on submission anyway. If you are confident your book is strong, then work on your query letter. Write a new one. Follow the #askagent hashtag on Twitter to learn more. Read agents' blogs and follow submission guidelines on agency websites very carefully. I know from agent friends that most submissions they receive are unprofessional in some way! I wish you loads of luck.
