Kirsteen Robson joined Usborne in 1997 with a background in music, education, and Christian publishing.

She loves the challenge of writing about anything from aardvarks to zombies. Marta Cabrol was born near Barcelona in 1976. She was very lucky to have a mother who worked in the library where she spent many hours reading lots of books. This was an important influence on her because it helped create a special sensibility to the world of images. Now for her own illustrations, she combines the children's world of imagination, storytelling, and reading, which have always been an important part of her life.
