She worked for several different publishing houses including Rights Director at Penguin Children’s Books before becoming an agent. As a partner at The Agency, Hilary continued to represent Michael Bond’s Paddington Bear alongside a wide range of children’s book authors and illustrators from pre-school books to YA novels – handling their publishing deals alongside their film, TV and stage rights.
