She's pretty enough to be popular, and Lord knows she's rich enough for it. But what society loves best about Gwen Maudsley is how very, very nice she is. So when a cad jilts her at the altar - again - an outraged London brays for blood. Only Gwen has a different plan. If nice no longer works for her, then it's time to learn to be naughty. When Alexander de Grey, a notorious rogue, takes Gwen on an educational tour through the glittering casinos of the Riviera, their friendship gives way to something hotter, darker, and altogether more dangerous - and Gwen must convince Alex that his wickedest intentions are exactly what she needs.
