A pact with the devil . . .

Miss Grace Banbury was in shock. Her mother put her up as a prize in a high stakes card game, and now the gentleman who won is ready to claim her! But Grace has other plans. She just needs the dastardly rogue to go along with it . . .

Yet there's no denying the attraction for the beauty standing before him, proposing an enticing wager: He will use all his charm and wit to seduce her into his bed . . . and she only has to resist. If she succeeds, she wins enough funds to secure her own future. If he wins . . . she'll be his. Daniel has never been so tempted—and he has no intention of losing . . .
