Jessica Trent arrives in Paris with one goal: rescue her weak-willed half-brother from the dissolute clutches of Sebastian Ballister, the Marquess of Dain, a hulking, notorious rake whose size and temper have earned him the nickname "Beelzebub." She expects to despise him. Instead, Jessica finds herself matching him insult for insult, and increasingly aware of the man beneath the monstrous reputation.
Dain has spent his life convinced he is exactly the beast society believes him to be, and Jessica's fierce independence and refusal to be intimidated infuriate him precisely because they intrigue him. Their sparring escalates from a country house party into an entanglement neither intended, forcing Dain to confront the self-loathing that built his armor and Jessica to decide whether she can love a man who does not believe himself lovable.
A classic of the historical romance genre, the novel is known for its witty, combative dialogue and its unusually vulnerable, self-aware "beastly" hero.
