Never Love a Lord by Regina Scott

He refused to court her once. Can she trust his intentions this time?

Spunky Petunia Bateman may be a commoner, but she is far from common. Anyone who cannot appreciate that is not worth her time. Then her best friend’s fiancé, the deposed crown prince of Batavaria, awards her a title, and the man she once loved decides she might be worth another look. Think again, sir!
Lord Ashforde had considered the lovely Miss Bateman for his bride three years ago. But his family history convinced Ash that cool heads and calm demeanors must prevail. There is nothing cool and calm about his feelings for Petunia, which have only grown since he rashly decided against her. But can he convince her, and himself, to give their love another try?
When the prince asks Petunia to persuade Ash to take up their cause to see their kingdom restored, the two are thrown together, and the enemies of Batavaria take note. Can love blossom amid skullduggery? Especially with an unlikely couple that might be made for each other?
