The Mésalliance - Rockliffe, #2

Reluctantly, the Duke of Rockliffe is in the market for a wife. His requirements are simple; a lady who will occupy her position with well-bred grace and chaperone his sister, Nell - but who will not bore him to distraction. He is acquainted with a number of ladies who could fulfil the first two but none who can achieve the last. Whilst accompanying his sister to what he speedily comes to regard as the house-party from hell, he meets Adeline Kendrick - acid-tongued, no more than passably good-looking yet somehow alluring; a combination that Rockliffe finds infuriatingly provocative.
Worse still, her relatives are quite deplorable - from Cousin Diana, a spoiled and ill-natured beauty, to manipulative and sadistic Uncle Richard. As a prospective bride, therefore, Adeline is out of the question. Until, that is, a bizarre turn of events cause the Duke to make what the Polite World world will call a mésalliance.
