Yours Truly, the Duke by Amelia Grey

Yours Truly, The Duke is the first novel in the historical romance Say I Do trilogy about dukes needing to wed to tap into their wealth by bestselling author Amelia Grey.

Fredericka Hale needs a husband, and fast. She’s been caring for her deceased sister’s three young children, and now a childless cousin has petitioned the court for custody. Fredericka is powerless to stop her, but having a husband might sway the ruling. The last thing Fredericka wants is a hurried-up marriage to a man she doesn’t know—much less love, but she’ll do it for the children. So when the handsome Duke of Wyatthaven shows up with a proposal, she accepts. He’ll help her, and in return, they’ll lead separate lives. But distance cannot keep them from their powerful attraction.
At the top of his game in London, the Duke of Wyatthaven has no interest in marriage. However, if Wyatt doesn’t marry by week’s end, he’ll lose a sizable inheritance from his grandmother. When Wyatt’s solicitor finds Miss Fredericka Hale, Wyatt considers this little hiccup solved. Miss Hale is lovely, and intelligent. Most importantly, she prefers country life to London, so he’s free to continue his life as usual. But when circumstances force Fredericka and the children to show up at the duke’s door, Wyatt can’t deny he’s always been under her spell. Will the duke give up his bachelor lifestyle and give into the fiery passion growing between them?
