Rosie Dickins grew up in England and Hong Kong. An avid reader, she always loved dreaming up her own stories. After studying literature at Oxford University, art in Paris and plenty of travelling, she settled in London, where she works for Usborne Publishing. She has written over a hundred children's books, from award-winning information books to fiction.

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.
