Catherine L Byrne amused herself writing as a hobby for some years until she had her daughter, but becoming a mum made her realise she now had a purpose and time was limited, so she must get on with writing seriously.
The winter of 2009 was severe and as she and her family live in a small village, they were house bound by unusually deep snow for southern England. So she settled down in her office (i.e. the corner of her bedroom) and began her first book, which was published in 2010.
She hasn't stopped writing since, generally on the theme of forbidden or unrequited love, and often including erotic scenes.
