With This Ring by Celeste Bradley

The Rules of Engagement
Elektra Worthington is the lovely middle daughter of the eccentric, impoverished Worthington family. Her beauty means nothing to her except as her currency to return the Worthington name to respect, security, and restoration of the family estate. To this end, she will stop at nothing, even if she must kidnap a rich lord in the process. If this lucky gentleman is just returning from a long absence and knows nothing of the Worthington reputation, well, a girl shouldn’t look a gift lord in the mouth…right?

The Price of Passion
Lord Aaron Arbogast, returning to England after a decade-old scandal. He will someday become the Earl of Arbodean and inherit the estate…if, that is, he can prove to his ailing grandfather that he is a reformed man. Falling for a woman like Miss Worthington could cost him everything. But his desire for her? Priceless…
