"Fiona Clayburn, a headstrong young noblewoman with a passion for art, has no interest in succumbing to the arranged marriage her father plans for her.

A fateful meeting with Giles Bancroft, an aloof young man and heir to the earl, presents a way out. Giles, like Fiona, wants nothing more than to stay single, so together, they hatch a scheme to achieve their common goal of avoiding marriage: pretend to be destined lovers!"--
