Vexing the Duke by Celeste Jones

Scandal forces them to marry…will another scandal tear them apart?
At their first meeting, she spat upon his shoe. Within a fortnight, they were wed.
When Miss Sarah Hancock causes a scandal in Boston, her father takes her to London in search of a husband.
At her first party, Sarah insults the Duke of Amherst who takes her over his knee to spank some manners into her. When his discipline comes to light, Sarah’s father offers him a choice: Marry Sarah or send her back to America where she has no prospects for a husband.
Intrigued by the spirited girl from America, the Duke proposes.
Despite the circumstances of their marriage, Sarah and Jeffrey form a bond and appear headed for a bright future. That is, until Sarah pretends to be someone she’s not.
