While still a journalist, she decided to have a go at writing a novel. This was Woman to Woman, which went straight in to the Irish bestseller list and stayed there for eight weeks. To date she has written 12 novels. Her books are number one bestsellers and are published in many countries around the world in English and in translation.
Cathy's new novel, Between Sisters, is published by Orion (October 2015).
Cathy is also an Ambassador for UNICEF in Ireland helping to raise awareness of the plight of children orphaned in Africa through Aids. She lives with her husband, John and seven-year-old twin boys in Co. Wicklow, Ireland.
.@SimonHarrisTD I'm STILL against #sistersofcharity owning the #NationalMaternityHospital https://t.co/gXKbxjNdHz via @UpliftIRL
RT @LisaHannigan: Over 50k now. Please sign and share if you agree that a religious order (who owes money for abusing women) shouldn't own…
RT @MarianKeyes: 2/2 So in accordance with that vow of poverty, perhaps they will give the Irish people the land for #ourhospital?
