A lady should avoid a scoundrel if she does not wish a lifetime of heartache. But sometimes hearts simply do not care about rules.

Luck strikes when least expected and Lady Vivian Winthrop finally gets a taste when an unexpected fortune is left to her and not her brother. But there’s a caveat: to keep it, she must marry within one year. As newspapers name her “Britain’s richest spinster,” men swarm her receiving room with hopes of charming her down the aisle. Vivian becomes frustrated by the incessant attention—and unfortunately, Vivian discovers she cannot identify true gentlemen from sneaky scoundrels like her own brother.

Her brother owes a shocking gambling debt to Edmond “Dantes” McNab, a scarred pugilist who owns a wild pub. With his ear to the ground, Dantes knows the truth about much of the ton. Vivian offers the man a deal he can’t resist: help her find a true gentleman to marry, and she will repay her brother’s debt in full.

It’s soon clear Dantes knows the scoundrels’ secrets because he is one himself. Unfortunately for Vivian, her heart becomes a bit too affected by the burly man. She knows well enough any affection for Dantes will end in nothing other than disaster. But sometimes one’s heart simply does not care about silly rules.

If Vivian doesn’t find a suitable gentleman soon, she may make the biggest mistake of her life and fall in love with one of the worst scoundrels in London.
