Dangerous waters. A journey adrift. Enough secrets to lift the ocean on rising tides. After learning the truth about her existence, Princess Luna discovers that her calling as a mermaid might not include the simple life she imagined with her future mate. Ryan's pirate family threatens not only the surface but also her home in the ocean. And taming a fleet of pirates isn't an easy feat. To do so, she must learn the pirate life and overthrow the pirate king. Adapting to a world of danger and destruction, Luna's nature as a peaceful mermaid is tested. She refuses to let pirates ruin everything the mermaid colonies have accomplished to unite the land and sea to save them from extinction. But she fears she must resort to the traditions of her shunned merman king father to survive a world that threatens her existence. If she does, she not only risks losing her future with Ryan, she also risks the lives of her land family and everything that makes her who she is.
