With hopes of evading a great sin in her past, Liza catches the next bus out of town and accepts a job offer at a small diner in Mystic, Connecticut. She aims to live a normal life, but she fears that whatever she has within her is too strong and unstable for her to control. Liza and her best friend Farah discover that Liza is a half-mermaid, dubbed 'demi,' and the only demi thought to have enough power to lead the battle against Maria the Sea Witch and her army of flesh-eating sirens. When Liza meets a handsome stranger named Edric, she starts to wonder if it's time to take a chance and open her heart to someone. There is always more than meets the eye, and that rings true in the small town of Mystic. The first part in a dynamic series, Mystic Waters will put to bed all preconceived notions about mermaids and awaken the idea that, beneath the blue horizon, there is a whole other world at war.
