Katherine Flynn has been an agent since 2008. Her clients are award-winning and #1 New York Times bestselling writers.  Recently, her authors have won or been finalists for the Pulitzer Prize, the National Book Award, the George Washington Prize, the Hillman Prize for the Common Good, and the Helen Bernstein Book Award for Excellence in Journalism, alongside numerous best-of-the-year selections and many other accolades.

Katherine represents history, biography, politics, current affairs, investigative journalism, narrative nonfiction, cultural criticism, pop culture, adventure, true crime, science, nature, medicine, business, sociology, and psychology. She also represents select fiction, and is fond of urban or foreign locales, crime novels, insight into women's lives, biting wit, and historical settings. That said, she is open to anything that is well-written and contains a good, fresh story or big idea. She prizes securing major deals for her authors with quality publishers and placing international and film/tv rights for their books.

Prior to establishing Calligraph, Katherine worked at the Kneerim & Williams Agency for fifteen years. She previously edited history textbooks, taught English literature and composition to high school students, and worked in a rare book shop. She serves as the publishing consultant to Harvard University's Radcliffe Institute and is a Boston Book Festival board member.
