Kelsey is currently booking for October, November, and December 2025.
It's wonderful to meet you! I'm Kelsey Klosterman, a book editor with a focus on fiction for young adult and middle grade readers. I also work on picture books, early readers, and chapter books, as well as adult and new adult books. I primarily work on contemporary fantasy, high fantasy, contemporary fiction, and speculative fiction, though I do work on other genres as well.
My most popular services are developmental editing, line editing, and copyediting for manuscripts. Once the book itself is ready to go, I help traditionally publishing authors with their query letters and story synopses, and I write jacket copy for self-publishing authors. I'm pleased to work with authors, literary agencies, and book publishers around the world.
I primarily edit novels, though I also periodically work on nonfiction and on projects other than books. If you're not sure if I'm the right fit for your work, please feel free to reach out!
I have professional editorial training at publishing houses and literary agencies alike, including the Charlotte Sheedy Literary Agency, Writers House, the Carol Mann Agency, McIntosh & Otis, and Peachtree Publishers. I hold a certificate in publishing from the Columbia Publishing Course, and I graduated from Emory University with high honors in English and creative writing.
The books I've edited have sold to the biggest publishers in the world, including Penguin Random House and Simon & Schuster. Will yours be next?
