Mermaid princess Serena barely survives the sadistic cruelty of her aristocratic fiancé, Julian, fleeing her underwater sanctuary for the lawless human oceans above. Desperate for sanctuary and safety from Julian’s naval pursuers, she accepts a transactional marriage proposal from Roderick, the formidable pirate king of the high seas. In exchange for armed naval immunity, Serena agrees to nurture Roderick’s motherless young daughter, Mira, aboard his flagship.
Life among the buccaneers proves far warmer than her golden cage, and Roderick’s fierce protective instincts slowly mend Serena’s battered spirit. But when Julian deploys royal warships to recapture his escaped bride and exterminate the pirate fleet, Serena must embrace her latent oceanic powers to defend her chosen family.
