With nearly fifty years' experience in publishing and editing, Wendy Sherman and Tracy Brown know books. Who doesn't want a book-savvy agency? If you're writing fiction, you should have a distinctive voice or strive to produce upmarket women's fiction like the work of Mary Sharratt (you can read an interview with her here.) Nonfiction should be narrative in the veins of history, current events, biography, memoir, travel, nature books, business, and psychology. No romance, however, and no children's. Sherman gives helpful advice on what your query letter should sound like, though: "Almost [like what the] flap copy for what the book is going to be."
