Lyon’s Lover by Maggie Sims

A wastrel lord and an ex-courtesan forced together must pay the price of their past sins.

She’s planning for the future…
Having enjoyed a successful career as mistress to various members of the Ton, Isabella Rossi longs to walk away from her past. She wants a normal life with all it entails—a husband, a home, and children. Isabella seeks out the Black Widow, owner of the Lyon’s Den gaming hell who also runs a specialized matchmaking service.

He’s living for the moment…
Heir to an earldom, Luke Lynwood is addicted to drinking, gambling, and avoiding his responsibilities. But when he gambles more than he can afford, the Black Widow offers him an alternative way to repay his massive debt.

Under Isabella’s reluctant tutelage, Luke must come to terms with his lack of self-control and face his father, which might just take a Christmas miracle.
