Moonlight and the Duke by Meara Platt

Handsome widower. Shy spinster. Will he be the one to give her a first kiss?
Connor Fieldstone, the Duke of Lynton, renowned as a Silver Duke, has no intention of ever marrying again. One failed marriage is enough for him, but he readily admits his heathen children need to be brought under control, especially now that his dowager mother has invited a horde of eager debutantes, young diamonds of Society, to a house party at his Devon estate for the purpose of finding him a perfect match. Not going to happen. He merely wants a governess to mind his children. Unfortunately, his children have scared off the fourth one in as many months just as this party is about to start. What is he to do but turn to his bookish neighbor, Lady Eden Darrow, for help?

Eden has adored Connor ever since she was a child and he rescued her from a tumble into his fishpond. Now, the handsome widower is a Silver Duke, one of those sinfully gorgeous, forty-ish bachelors with a dash of silver in their hair. They are looked upon by Society as Greek gods, completely unattainable because of their determination never to marry—or remarry, on Connor’s part. When Connor pleads with her to help him out with his children in exchange for helping her find a suitable match, she accepts. What has she, a twenty-seven-year-old spinster who has never been kissed, to lose? What she does not expect is to suddenly become the belle of the party, drawing the avid attention of several potential suitors…and is it possible Connor is one of them? Will he be the one to give her a first kiss? She wants it to be a moonlight kiss. Is he willing to give her moonlight and more?
