Peter Bunzl grew up in South London in a rambling Victorian house with three cats, two dogs, one sister, an antique-dealer dad and an artist mum. He is a BAFTA-winning animator, as well as a writer and film-maker. Peter's debut novel, Cogheart, has been shortlisted for lots of awards, including the Waterstones Children's Book Prize. Like Lily and Robert, he loves adventures and reading penny dreadfuls, but wishes dearly that he had a mechanical fox called Malkin.
