Kate Castle

Kate Castle is the author of the best-selling young adult adventure novel Girl Island, winner of two Golden Crown Literary Society Awards. She has just released her debut collection of poetry, The Nature of Love, and her next novel, Letters From the Apocalypze—a zombie apocalypse thriller—is out in 2025. Kate’s books fall into the young/new adult adventure and thriller categories and always feature a sapphic romance subplot. Kate is passionate about representing LGBTQ+ teenagers in literature and writes immersive, fast-paced stories populated with fierce, independent, queer young women—the kind of characters she wished she could have read more about growing up.
