Once Upon an Anniversary Party

Brielle Duncan can hardly believe her boss has volunteered her to plan the company's fiftieth anniversary party when the most challenging things she's ever had to plan have been what outfits to wear to work, but there's no way she can get out of the assignment. And when she learns her co-planner is none other than Decker O'Leary, the company serial dater, she is beside herself. How is she supposed to work with this man to plan a party for over four hundred people? Decker O'Leary knows his boss is a moron, but for once he's done something right in assigning Decker to work with Brielle Duncan.
The fact Brielle makes her contempt for him obvious in the way she looks at him doesn't matter, because he knows one thing. He's going to find out just what it is he's done to make her feel that way, then he's going to change her mind.
