After losing her parents, Laria Losstree is saddled with a mountain of bills. Enter the archvillain, Duke Icardes, who agrees to pay off her debt, but only if she’ll marry his son, Evan.

But when the duke starts acting suspiciously nice to her, Laria begins to wonder if he's on to her plan, and a battle of wits between archvillain and daughter-in-law begins!
