She also writes under the pen names Katherine John/ K. A. John (crime novels), Katherine Hardy (novelisations of television programmes) and Caro French (modern fiction).

As well as novels, she writes short stories, plays and non-fiction, and has had work published in magazines including Woman, Woman’s Own and Woman’s Weekly.

Ty Catrin, an adult education centre in Pontypridd, was named in her honour in 2002. -wikipedia
