When the successful British mystery writer Judith Moore meets Gavin, a handsome and charming baron, at a birthday party on the Cornish coast, his love transforms her from a bitter, lonely young woman into a romance heroine overnight. After a whirlwind honeymoon in Paris, he whisks her away to a secluded Gothic castle. But soon she finds herself trapped in a nightmare, as her husband's mysterious nature and his alternation between charm and violence become increasingly frightening.

As Judith battles both internal and external demons, including sexual ambivalence, psychological self-torture, gaslighting, family neglect, alcoholism, and domestic abuse, she becomes increasingly addicted to her wild beast of a husband. Why do women stay in abusive relationships? The answer can be found in the tortured mind of the protagonist, whose richly layered fantasy life parallels that of the female Gothic romance reader. Filled with dark humor and evocative imagery, Bluebeard's Castle is a subversive take on modern romance and Gothic erotica.
