Books one through four of the best-selling Dukes of War series: 

The Viscount's Christmas Temptation

Certain individuals might consider Lady Amelia Pembroke a managing sort of female, but truly, most people would be lost without her help. Why, the latest on-dit is that rakish Viscount Sheffield is canceling the fête of the year because he hasn't time for silly soirees. He doesn't need time - he needs her! 

The Earl's Defiant Wallflower

Oliver York returns from war to find his father dead, his finances in arrears, and himself the new Earl of Carlisle. If he doesn't marry an heiress - and fast! - he and his tenants are going to be pitching tents down by the Thames. He definitely shouldn't be trading kisses with a penniless debutante...no matter how captivating she is! 

The Captain's Bluestocking Mistress

Spinster Jane Downing wants off the shelf and into the arms of a hot-blooded man. Specifically, the dark and dangerous Captain Grey.

Miss Daphne Vaughan hates that crying off her fake betrothal will destroy Major Blackpool's chances of finding a real bride. She plots to make him jilt her first. Who cares if it ruins her? She never wanted a husband anyway. But the major is equally determined that she break the engagement. With both of them on their worst behavior, neither expects their fake betrothal to lead to love....
