Katherine’s research focuses on literature of the fin de siècle and the works of Henry James, especially those from the middle and “major” phases of his career. She is the author of Joan: A Novel of Joan of Arc (Random House US / Hodder & Stoughton UK), which won the 2023 American Library in Paris Book Award and has been translated into nine languages, and Mary B (Random House US). Her essays and reviews have appeared in The New York Times Book Review, the Times Literary Supplement, The Telegraph, The Washington Post, The Wall Street Journal, The Chronicle of Higher Education, The New York Times, The Los Angeles Review of Books, The Minnesota Star Tribune, Electric Literature, Literary Hub, and other publications, with forthcoming work elsewhere. Her next book, which is under contract with Random House, will explore through a realist lens the complex and violent world of Arthurian legend, in particular, the sibling dynamic between Morgan le Fay and King Arthur.
