Kathryn is an active member of the Society of Authors; she contributed a poem, A Mother's War Song, to the Frances Lincoln anthology, Lines in the Sand (2004), which highlighted the plight of children in the conflict in Iraq; and she wrote a short story, Roman Gladiators, for inclusion in Scholastic's Wow!
The anthology featured 366 short stories, each of 366 words and was aimed at helping literacy, with proceeds from the book being donated to Childline.
In 2009 Kathryn was one of a group of authors pressing Somerset County Council to maintain its funding of the Children's Library Service.
Also during this period, Kathryn wrote her first work for Egmont, entitled Snowshoe the Hare (illustrated by Ruth Rivers), which was published in 2005.
In 2006 and again in 2009, Kathryn performed at the Edinburgh International Children's Book Festival, where she presented a mix of fun, animal mask-making and stories in the Workshop Tent.
