In To Barcelona, With Love, Erica, an American expat living in Barcelona who translates novels into Spanish, though her dream is to be published herself someday.  Anna is the American author of the book Barcelona, Mi Amor that became a big hit after Erica's translation.  Due to its local popularity, Anna comes to Barcelona for a book signing event.  Her arrival not only catches the attention of local bookstore owner Nico, for whom Erica has long had feelings, Anna's appearance at the store threatens to bring to light Erica's secret – she took liberties with her translation to improve the story and infuse it with the local authenticity it was missing.  As the two women become friends over the course of Anna's visit, they ultimately help each other embark on a path to find their true happiness.

To Barcelona, Forever begins five months later and follows Erica and Anna as they are happily navigating new chapters in their lives.  This time the friends find themselves traveling outside the city of Barcelona to a charming village where a misunderstanding leads to unexpected romance for one of them.

Liara goes to Italy and impulsively buys the villa where her parents met. She soon learns she is in way over her head and must ask a lawyer-turned-handyman to help her renovate.
