Can the Ladies of the Wagering Whist Society help sort out a love quadrangle?

It's not that the practical Beatrice Kendrick doesn't trust her mirror twin, the vivacious and flirtatious Isabel. It's just that the rebellious Bel has proven herself all too capable of welcoming the attentions of the wrong sort of man. So to keep Bel from getting into trouble, Bee secretly accompanies her when she makes her debut in Regency London. Can Bee shield her own heart while trying to protect her sister? And can Bel ensure that her quiet sister gets a taste of the joys of London society – and a chance at romance?

When the broodingly romantic Edward Conway, nursing a broken heart, meets musically inclined Bel Kendrick, she stirs a passion in him he wasn't sure he could ever feel again after the death of his Italian lover. The strappingly handsome Paul St. Vincent, too, meets the thoughtful and clever woman he thinks is Bel, and she seems to be just the sort of intellectually-minded woman he's looking for. Only sometimes Edward senses that Bel doesn't always remember what they'd discussed the last time they met. And at times she is entirely too giggly for Paul's taste.

Both men, however, have decided that Miss Kendrick is the right woman for him. What they don't realize is that they're both right. But it will take a little sleight of hand by the ladies of the Wagering Whist Society to untangle this trick of mirrors.
