California Mermaids Books in Order

The California Mermaids series is a historical fantasy romance set along the California coast in the early twentieth century. It begins with Oceania, a young mermaid who has waited for her eighteenth birthday so she can finally visit the world above the sea in human form.

That freedom comes with a deadline.

Oceania belongs to a family marked by a long-running curse. After turning eighteen, each affected mermaid has twelve moons to decide whether to remain on land or return permanently to the ocean. It is not a small choice. One life means new possibilities, human love, music, and cities. The other means home, family, and the world she has always known.

In The Mermaid's Curse, Oceania meets Xavier, a young man on land who hopes to become a composer despite his wealthy father's plans for him. Their connection is built around music as well as attraction, and it gives Oceania a reason to imagine a life she had never expected. But the curse makes every step toward Xavier feel risky.

The Mermaid's Wedding continues Oceania and Xavier's story as they make plans for a life on land. The series keeps the pressure on the couple by asking whether a relationship between two people from different worlds can withstand the demands placed on them by family, history, and magic.

The final book, The Mermaid's Secret, moves forward to Roaring Twenties San Francisco and follows Doria, Oceania's niece. Doria wants to visit her aunt and uncle, now known as jazz musicians, but she inherits the same painful choice between land and sea. Her journey introduces a new romance, a devoted merman who follows her to shore, and the danger that someone may discover what she really is.

It is a family curse with a romantic cost.

The series blends fairy-tale rules with period details, including 1912 California, jazz-era San Francisco, and the world of speakeasies. Music matters throughout, both as a talent and as a way characters recognize something important in one another.

Readers can begin with The Mermaid's Curse for the fullest picture of the curse, Oceania's choices, and the family history behind Doria's later story. The books are romantic and lightly adventurous, with the biggest tension coming from identity, loyalty, and the question of where each heroine truly belongs.
