The final two entries in THE HEIRS OF THE ARISTOCRACY series make up this boxed set of four young men and women and their struggles with courtship. In THE HONOR OF AN HEIR, twin sisters Dahlia and Diana have no desire to husband-hunt, but their ghost of a father has plans for them and the set of twin men who would make their perfect mates. Heir to a sultanate, Ertugrul  hasn't yet begun his harem, but if he finds true love with a young lady in London, he may forgo concubines.
His best friend David's sister Adeline has someone in mind-Lady Rose, a duke's daughter-but Ertugrul surprises everyone with his choice in THE ROSE OF A SULTAN'S SON.
