About Kate

Kate Castle is an English writer. She is best known as the author of the best-selling young adult adventure novel Girl Island - winner of two Golden Crown Literary Society 'Goldie' Awards (Debut Novel and Young Adult Fiction) and two Lesfic Bard Awards. Her next novel, The Coven - a dark, dystopian new adult adventure - will be released in 2026.

Kate's books fall into the young adult and new adult adventure, thriller, and horror categories and always feature a sapphic romance subplot. Kate is passionate about representing young LGBTQ+ females in mainstream literature and writes immersive, fast-paced stories populated with fierce, brave young women - the kind of characters she wished she could have read more about growing up.

Kate lives in Colchester, England, with two cats and a dog called Teddy.
