"So what do you say to the wager, Miss Prentess? A diamond worth thousands against a night with me?"No London beauty has managed to tame the incorrigible Jasper Coale, though many have lost their reputations trying. In sedate Bath on a family errand, the viscount expects to find little in terms of entertainment—certainly no female company to tempt him.Miss Susannah Prentess's discreet card parties in Royal Crescent offer a welcome distraction. And the glint in Susannah's hazel eyes tells Jasper he's met his match at last. But is she game enough to accept the most outrageous wager of all?
