Susan moved to Ireland for twelve months — in 1998. Having gained a Master of Philosophy in Irish Theatre Studies from the Samuel Beckett Centre, Trinity College, she embarked on a career in theatre criticism, eventually moving into feature writing on all things cultural.

Writing as Susanna Allen, her new series The Shapeshifters of the Beau Monde has been signed with Sourcebooks thanks to Julie Gwinn. The first novel, A Wolf in Duke's Clothing is set to debut in April 2021.

She is the author of Drama Queen and The Fidelity Project, both published by Headline UK, and That Magic Mischief, via Crimson Romance. Her current book, Many Brave Fools: A Story of Addiction, Dysfunction, Codependency… and Horses is published by Trafalgar Square Books.

Susan is living her life by the three Rs: reading, writing and horseback riding.
