Louie Stowell started her career writing carefully-researched books about space, Ancient Egypt, politics and science but eventually lapsed into just making stuff up.

She likes writing about dragons, wizards, vampires, fairies, monsters and parallel worlds. She lives in London with her wife Karen, her dog Buffy, and a creepy puppet that is probably cursed.

Lucy Bowman grew up in a village in Cheshire, where she spent her time having adventures outdoors or reading about them in books.
