A Marriage of Inconvenience — Susanna Fraser

Lucy Jones is a nobody. As an orphan she was reluctantly taken in by her wealthy relatives, the Arringtons, on the condition that she be silent and obedient, always. When her lifelong infatuation with her cousin Sebastian is rewarded by a proposal of marriage, she's happy and grateful, even though the family finds excuses to keep the engagement a secret.

James Wright-Gordon has always had the benefits of money and a high station in society, but he is no snob. He's very close to his sister, Anna, who quickly falls for the dashing Sebastian when the families are brought together at a wedding party. Meanwhile, James is struck by Lucy's quiet intelligence, and drawn to her despite their different circumstances in life.

Lucy suspects that Sebastian has fallen for Anna, but before she can set him free, a terrible secret is revealed that shakes both families. Will James come to her rescue -- or abandon her to poverty?
