A Duke Makes a Deal by Matilda Madison

When this duke wins a wife, all bets are off.

When nouveau-rich Clara Woodvine attends her first high society ball, she’s expecting it to be the most wonderful night of her life. Unfortunately, it turns out to be the worst. When Clara overhears her would-be fiancé has bet her and her dowry away in a card game to the Duke of Combe, aka the Divorced Duke, all hopes for a happily ever after seem lost.
Silas Winters, the Duke of Combe, has spent over a year brooding in misery after the end of his toxic marriage. Saddled with crippling anxiety and the reasonability of recovering Clara’s reputation, Silas proposes a marriage based on friendship and nothing more. Clara accepts, but only on the condition that she understands this is a marriage of convenience because Silas is determined never to love again
But when the past comes back to haunt them, will Silas realize that love is something he can choose? And will Clara be able to stand up for those she loves, even if she must do it alone?
