After eight years, Lucy Endcott has finally returned to London to visit her dying father, a cold disciplinarian who never approved of his eldest daughter. Lucy is a respected widow, residing in the countryside away from the wicked excess the city has to offer and her unscrupulous ex-lover, the Marchioness Irena de Macey.

When Lucy finds out her youngest brother has gambled away his inheritance at the Pythos Club, she enters the den of iniquity in order to save him. Inside the club she meets the owner’s alluring daughter, Tisha McGrath, who is more than willing to help her brother…for a price.

Tisha longs to introduce Lucy to those secret passions she's kept hidden away for so long. But dark secrets and transgressions from the past connect their families in shocking ways. Both women will work together to resolve this scandal before it unravels further but Irena is waiting for the right moment to strike, and Lucy may have no other choice but to give into Irena’s demands in order to save the ones she loves from utter ruin.
