About Us

The Short Version

Arian Derwydd Books, LLC, is the brainchild of Katherine Johnson-Cook. Katherine writes as Mychael Black (LGBT+), Carys Seraphine (m/f), and Katherine Cook (fantasy). She decided to start Arian Derwydd Books to publish many of her books she couldn’t find a suitable home for elsewhere.

Behind the Name

With a Welsh (actually, Celtic all-around) ancestry, Katherine chose words from the Welsh language to name her publishing company. ‘Arian’ means silver, and ‘Derwydd’ is the word for Druid.
