Thank you for giving me the opportunity to review your manuscript. I don't feel this is a project I can take on at this time.
As I conduct legal practice in addition to my work as an agent, I am forced to be very selective in both the number and kinds of literary projects that I take on to represent. While I am eagerly looking for quality commercial fiction, I ultimately concluded that your writing was not that engaging, and I felt your dialogue was weak. You should certainly not interpret my decision as the final negative assessment of your manuscript. As you know, this is a most subjective business and most agents, I believe, take only those projects that they personally feel strongly about and most confident in selling. Other agents may well assess your manuscript differently.
I wish you the best in finding strong representation for your work, and thank you again for giving me the opportunity to consider this project.
