She returned to England to put him in his place—not to put herself in his bed.

Alec Douglas, Duke of Lionwraith, a war hero betrayed on the home front while he was away at battle, trusts no one and prefers his solitude. But when his sister begs for help because she is ruined, he vows to make the man responsible pay. When the vile rakehell proves impossible to find, Alec isn’t swayed. He can just as easily destroy his enemy with a subtler attack. The Marquess of Ardsmere’s business provides the best wines and rarest imports to the finest houses in all the realm—but by the time Alec is finished, West Belgium International will cease to exist.

But the despicable marquess can’t be the ruination of Alec’s sister, because the man does not exist. However, Lady Francis, better known as Frannie and sometimes as the Marchioness of Ardsmere, is quite real. Born in Belgium after a terrible accident killed her father, Frannie was introduced to the world as the family’s ward rather than an Ardsmere daughter, and a fake Ardsmere son was fabricated for her to marry to keep the wealth, lands, and privileges of the title away from a heartless cousin. The ruse has served quite well, but now some quarrelsome duke threatens everything because his lightskirt sister tossed her reputation to the wind and ridiculously named the pretend marquess responsible.

Frannie is not about to lose her lucrative empire or expose herself as a fraud. There’s naught to be done but assume her usual role as the imaginary marquess’s wife and put the deplorable duke in his place. However, when she meets Alec’s sweet, trusting sister, she can’t bring herself to finish the poor girl off or take down her handsome brother. Cursing her soft-heartedness, Frannie agrees to help Alec. Not just because he’s a tempting challenge she can’t resist, but also because his sister is kindness itself.

While tracking down the real foe responsible, Alec and Frannie come together in a complicated dance that not only risks riches and reputations but also their hearts. Frannie’s life of lies has always provided everything she needs—except love. What’s she to do when the man who steals her heart despises anything that isn’t true?

What do a skillful liar and a man drowning in bitterness have in common? Loneliness and pent-up passion. An exciting combination until secrets are revealed and everything falls apart.
