For as long as anyone can remember, Florence (Rory) Kensington and Flynn Parks have contentiously coexisted in their respective roles. Rory, as the responsible, poised heiress determined to make a difference. Flynn, as the carefree life of the party who considers having fun a full-time profession. Years of close proximity and overlapping social circles have only strengthened their mutual antipathy, which now seems ironclad. Until Rory finds herself without a fiancé and Flynn finds himself in need of one. She's sick of being seen as a boring workaholic. He needs a bride his finicky father will approve of. For the first time, they agree on something-a mock engagement will benefit them both. After all, who better to stick to the terms of an agreement than two lawyers? Except ... pretending to be a couple is unexpectedly easy, and the longer they pretend, the harder it is to distinguish reality from fiction. Suddenly, their straightforward deal seems anything but ... Was it all lies? Or has a love story been buried beneath the animosity all along?
