Natalia and Lauren O'Hara are sisters from the north of England. In the daytime they edit scripts and design sets, and at night they draw and write together. As children they loved fairy tales, animal fables, and the stories their Polish grandmother told on snowy nights. Frindleswylde is their third collaboration after Hortense and the Shadow and The Bandit Queen. Natalia lives in London. Lauren, who is also the illustrator of Sophie Dahl's MadameBadobedah, lives in Dublin.
