THE GIRL WHO WOULD BE QUEEN Nerissa Marin hides among teens in her human form, waiting for the day she can claim her birthright—the undersea kingdom stolen from her the day her father was murdered. Blending in is her best weapon—until her father's betrayer confronts Nerissa and challenges her to a battle to the death on Nerissa's upcoming birthday—the day she comes of age. Amid danger and the heartbreak of her missing mother, falling for a human boy is the last thing Nerissa should do. But Lo Seavon breaches her defenses and somehow becomes the only person she can count on to help her desperate search for her mother, a prisoner of Nerissa's mortal enemy. Is Lo the linchpin that might win Nerissa back her crown? Or will this mortal boy become the weakness that destroys her?

They say that love is the death of duty … Speio Marin is land-bound, tied to the side of the Waterfell queen-to-be, Nerissa. There's only one problem—she wants nothing to do with any of the Aquarathi or her undersea kingdom, preferring instead the freedom of pretending to be human. Torn between his own desires and his duty to serve his future queen, he spirals into an abyss of malcontent. Speio’s mistrust of humans is no secret, and he sees them only as a threat to the existence of his people. Until he meets Anya Delmonico—a mysterious and enigmatic girl, teetering on the edge of survival. Anya is sedate and secretive, yet reckless enough to brave a hundred-foot cliff jump. Caught between a dark past and an ex-boyfriend who refuses to let her go, Anya knows that getting involved with anyone new is the last thing she should do. But when her past catches up to her, Speio turns out to be the only one she can trust, refusing to let her face her demons alone. When Anya discovers the truth about Speio, putting her life in mortal danger from the Aquarathi as well as her own sinister pursuers, will he risk everything to protect her? Or will he choose duty above all?

The coronation is over. But the battle has just begun. Nerissa Marin has won her crown. But can she keep it? Already, her ties to the human realm are driving a wedge between Nerissa and her people. When word arrives that her part-human prince consort, Lo, has been poisoned, she makes the difficult choice to leave Waterfell and return landside. As the royal courts debate her decision, even more disturbing rumors surface: a plot is rising against her, led by someone she least expects. On land, Nerissa learns another shocking truth: �Lo does not remember who she is. As her choice to try to save him threatens her hold on her crown, changing loyalties and uncertainty test her courage in ways she could never have imagined. Nerissa will have one last chance to prove herself as a queen …and save the undersea kingdom she loves.
