Wicked Wager

When hardened gamester Marcus Revington wins Horngate Manor in a card game, he's delighted to finally own property, and undeterred when he learns he must marry the heiress of the estate to claim it.
The heiress, Penny Montgomery, is happy with her life raising horses at Horngate and has no desire to wed anyone. When she discovers what her guardian has done, she comes up with a scheme to convince Marcus she's unsuitable as a wife so he'll give up his plan to marry her.
Who will win in this battle of wits and wills? Or will they both discover the name of the game is love?
