My Wicked Earl by Kathleen Ayers

Lady Miranda Reynolds has finally decided to wed.

Once the most sought-after young lady in London during her first Season, Miranda is now deemed unsuitable. An unfortunate scandal, as well as her own lack of interest in marriage, has led to a limited field of suitors. She’s narrowed her choice down to either a fortune-hunting dandy or an elderly rake.

Neither man is appealing, but Miranda is tired of waiting.

Colin Hartley, the Earl of Kilmaire would never return to the dubious bosom of the ton if he didn’t need an heiress to replenish the Kilmaire fortunes. He’s not particular about his future bride. The less he cares for her, the better.

Affection will not be involved. Colin gave his heart once with disastrous results. He doesn’t want to see Miranda, the woman who spurned Colin so she could marry a future duke six long years ago.

Except Miranda didn’t marry a duke. Or an earl. Or anyone, since she and Colin parted. Upon his return to London, Colin finds Miranda’s reputation tarnished, and she’s intent on marrying a gold digger who has terrible taste in clothing and wears too much pomade.

Colin shouldn’t care whom Miranda marries. He can’t forgive her.
If only he didn’t still want her.
