The Flirt:

Lady Willow Douglas holds the power of persuasion and can charm any man to do her bidding. But when her skill doesn't work on Sir Conrad Lockwood, he becomes a thorn in her side. The autumn festival is about to start, and Willow is distracted from her duties of being in the queen's secret society called the Followers of the Secret Heart - a group of strong women. Instead, she decides she wants to find a husband from all the rich, single, eligible noblemen who are arriving at the castle. But to her dismay, she discovers that her father, Rook (Legendary Bastards of the Crown) has hired Sir Conrad as her guardian until his return.

The Guardian:

Sir Conrad Lochwood arrives at the earl's festival, hoping to find a ward for his sister since the death of their parents. What he finds instead is the haughty girl, Willow, that he remembers from childhood that he used to pull pranks on just to make her scream. In exchange for what he wants, he promises Willow's father that he will watch over her until his return from Scotland. But Willow has turned into a beauty through the years and he finds himself attracted to her. Keeping her away from the men is going to be a challenge.

When a visiting earl's prize ruby is stolen, Willow takes it as her personal goal to find the thief. But Conrad's challenge is to keep her away from the men . . . and hopefully closer to him instead.

Can a strong woman who is determined to catch a thief accomplish her task before a dashing knight steals her heart away?
