In Regency London, Lady Alexandra de Montmorency risks scandal and ruin by assuming a masculine identity to protect everything her family owns. Known to the ton as a poised and fortunate gamester, Alex moves through high-stakes social circles with practiced confidence. Her carefully maintained disguise is threatened when Lord Wrotham begins to see through the performance, drawing her into a private contest of wits and attraction. As the danger of exposure grows, Alex must weigh the security of her inheritance against the possibility that the most perilous wager is not at the card table, but in surrendering control of her own heart.
