Orphaned pianist Allegra Brown is a poor relation with nothing much to recommend her, save a minuscule dowry and a very big imagination. She has spent the past several years as governess to her younger cousins, who are now ready for their come out—and want Allegra to marry, too. Specifically, they eagerly await the return of Allegra’s dashing, handsome, swashbuckling, conveniently absent and secretly fictional fiancé, the dread pirate Captain L’Amour.

Much like passion burning between him and a certain wildly unpredictable spinster, who seems to have confused him for a dashing, exciting pirate. By fulfilling her fantasies, can his dreams come true…together?
