Dukes Are Forever by Bec McMaster

A compromising situation forced him into marriage. But has his wife been working for the enemy all along?

In a steam-fuelled world where vampires once ruled the aristocracy, the Duke of Malloryn knows his nemesis, Lord Balfour, has finally returned to enact his plans of revenge.

Malloryn can trust no one, and when incriminating photographs surface—of an enemy agent stealing a kiss from his wife—he is forced to question just why his wife, Adele, trapped him into marriage.

Is she an innocent pawn caught up in a madman’s games, or is she a double agent working against him?

The only way to discover the truth is to seduce her himself…

Adele Hamilton may have agreed to a loveless marriage in order to protect herself, but that doesn’t stop her heart from yearning for more.

Her husband promised her a cold marriage bed. He swore he’d never touch her. But suddenly he’s engaged in a campaign of seduction—and the only way to keep her wits about her is to fight fire with fire.

The ruthless beauty has locked her heart away, but can she deny the passion that flares between them? And when the truth emerges, will she be the only thing that can save Malloryn’s life?

Or the weapon his enemy will wield against him?
