She began her writing and acting career by touring theatres and schools all across the UK and Ireland, working as a storyteller.

Ada Grey grew up in a doodling household with parents who ran a small chain of bookshops so it was no surprise that she went on to study and work as an illustrator. Ada began her illustration career working on cards, gifts and stationery before turning her hand to children's books. She is now best-known for illustrating the best-selling The Royal Baby series by Bloomsbury. More People To Love Me is Ada's first book with Macmillan Children's Books. Ada works and lives in Brighton with her daughter and cat named Tiger.
