Mermaid's Lullaby

Princess Thialissa is a little in over her head. Being the princess of the Ocean kingdoms, she is required to spend three months as a human to learn about them, and how to protect the mermaid race against them. Only three and a half months separate her from her eighteenth birthday as well as her Lullaby ceremony. Murderous sirens and a curiously familiar human who reminds her of her lost childhood friend Aquinesse are all part of her unforgettable journey to becoming queen.
